How to disable required password on bootup

Ok so if your phone reboots or crashes, you will need to enter a password or pattern in order for the phone to work. Even alarms and everything won't work until you enter the password. That's pretty bad especially if you NEED an alarm
Some people mentioned turning it on and off and it would give you a prompt to disable it.
But for us rooted people, it doesn't give us that option. And our data is unencrypted right?
Is there a workaround if I install a custom rom?

The phone is only unencrypted if you unencrypted it. I didn't decrypt when I rooted, and a few days later TWRP was made to support the 6p without decrypting. I don't know about alarms not working when locked, mine works fine every morning and I usually after to enter my PIN or scan my finger when I tap on a notification. I was using Smart Lock with my Pebble Time, but even that still requires a PIN again after 4 hours (I'm not using it for Smart Lock anymore because the fingerprint scanner is so convenient).
If you're referring to the "please enter PIN to continue booting" part, go to security settings when tap your method (mine is PIN) and I am asked if I want to require a PIN to start the device. This will require you to put in your PIN while Android is booting up and won't proceed unless the PIN is entered. THIS would cause you to lose all ability to use the phone such as alarms or emergency calls. I would toggle this OFF ("no thanks"), and it will still require an actual PIN (fingerprint won't work) for the first unlock after a reboot.

I believe the OP is talking about how it requires pin on the initial lock screen after booting up. Not even finger print or any smart locks will bypass, you have to enter the pin. As far as I know, the phone is functional at this point, so alarms and calls/text etc should come through.

Correct, as I stated in the last sentence of my post. My phone is completely usable in this state. I can read and dismiss notifications, but if I tap on one to launch that app, I have to unlock with PIN. Imprint won't work. I have a Tasker profile to launch Spotify when I plug in my headphones at work and it runs just fine after a reboot and before I've unlocked.

After Power ON, MUST use Knock Code first instead of fingerprint?

Anyone else seeing this behavior? On my 995, whenever I restart, or power on my phone.. I have to use the Knock Code to get into my phone, and it says "fingerprints unavailable for use" or something to that effect.
I find this odd behavior.

Its not odd behavior its LG behavior.
Unfortunately there's no way around it.

turn off secure startup in security...

Your fingerprint is encrypted and you phone can't access encrypted data until you unlock it after a reboot. So its kinda a catch 22 where you will always have to unlock with a pin after startup instead of fingerprint. Your fingerprint is biometric data and obviously can't be changed so it needs to more secure on your phone than your pin which you can change. It is this way on most phones with fingerprint readers.

It's not just LG, my Samsung S7 and Note 7 both required pin code on first log in after a reboot/boot up
It's part of Android now.

It's not even Android. My work phone is an iPhone and it has the same behavior. Which drives me nuts because our work phones require us to change pin codes every couple of months and we can't recycle codes.

I turned off secure startup as I don't need kids messing with my phone and I imagine after ten attempts if wipes it?

If I'm right, the op is taking about setting the fingerprint to unlock but it still requires the pattern. You will notice this if you use a third party app or launcher to lock screen. E.g. Nova launcher double tap to lock screen. It will tell you fingerprint is unavailable.
A work around to this is to doubly tap the top part of the screen (the bar where the date and signal strength is).
This will allow you to unlock with fingerprint.
If you use the stock lg launcher then double tapping anywhere on screen shows you to unlock using fingerprint.

I'm working with a developer of Screen Lock Pro to try and find a workaround for this. Currently his app will work on Android 5 and 6 by delaying the lock for 5-10 seconds but it's currently not working on Android 7 on LG (it is working on Pixel and Nexus devices).

Hmmm... Not sure I understand this behavior. My fingerprint is much more complex than a 4-digit code that can eventually be brute-forced (phone wipe or not - in theory I mean).. so why wouldn't my fingerprint be the top-most factor in unlocking the phone? I mean.. say I'm one of those guys that uses his last four of an SSN like an idiot, and someone knows that about me.. boom, they're in my phone. Do iPhones do this for real (as stated above)?

Yup, every time I restart my iPhone, it asks for my pin number and the finger print reader is inoperable. Even when I don't restart my iPhone for a while, it will occasionally lock out the reader and require a pin to wake.

Had to figure out where in the menus to dig through to find out who it is. (I seriously do not like how Apple sets their phones up.) Looks like it is AWMDM.

I always assume as much. Not really a bother for me. The iPhone is a work phone that I don't like carrying or touching. My personal phone is always my go to for anything unless it is work related.

I have this on my nexus 6p also. When ever i reboot the phone it requires me to use my pattern to unlock. It's a "feature" of sorts. Not going to go into my thoughts as to why but i think i may understand why they did that.

In case anyone is wondering, a few conditions that force you to use backup method are being left alone (with no smart locks enabled or active) for 4 hours, a reboot, and a failed scan 5 times in a row.
The reboot case is due to encrypted data (no matter what you do, your phone is encrypted on boot, unless you fix that, however, you phone will still treat it as such). The only reason I can imagine for the time out is in case a ninja chops off your fingers in your sleep. As for the wrong input, that seems annoying sure, but odds are if you got the fingerprint wrong 5 times in a row, it's not you.

Yeah v10 does this as well on fresh boot ups.
I'm not sure I understand the reason behind it I would think it would be less secure this way.

I'm not sure I'm following as to why encryption matters. Are you saying my fingerprint data is encrypted? If so, why isn't my PIN also encrypted?

Speaking of fingerprints has anyone run into the issue where the phone "forgets" your print? I have had this happen at random times and while the fingerprint data is still saved the phone fails to recognize my finger so I have to set it up again.

Lock Security Not Working

Is there anyone experiencing that no matter what lock I use, my phone always allows me to just swipe up once to unlock? I tried facial unlock & that works flawlessly, but I also added the secondary pattern and I still swipe up once and my phone just unlocks completely. I also disabled facial recognition with just primary pattern or number lock as the security and the phone still opens right up like no security is on it at all.
Anyone have a solution for this or does this seem like another bug for a future update?

Settings>Display>Navigation Bar>"Unlock with home button" - is this enabled or in any way related to what you're experiencing? Just a guess

I just took a look and that option is off. the kick screen doesn't skip. I have to swipe up Everytime...let's me right in

Do you allow Smart Lock on a network or attached device? What you're describing is the phone's behavior when connected to a Smart Lock approved device.

That's what is doing it. I had my Asus Zenwatch 2 listed as a trusted device in Smart Lock and my phone was doing the same thing. I removed all trusted devices and now I have to use my pin, finger print or irises to unlock my phone.

It is set to not turn on the lock when the screen goes off for 10 minutes by default. You have to go I to lock screen, secure lock settings

Welcome
Sent from my wickedly kewl Galaxy S8 using my fingers. Duh!!!

So it's this a bug? Trusted devices should unlock only when phone is connected or in vicinity to them.

Also seeing this same behaviour. My home wifi is a trusted device and obviously it unlocks when I'm connected to it, but now for the second time I've been away from home for over 2 hours and it happily unlocks with just swipe. It only asks for biometrics if I reboot the phone. So it seems that there's a bug in trusted sources whereby it believes its still connected to wifi for some time after you disconnect!

I had to disable my trusted place (home) even though I was 100km away to fix the issue.

Lock Security not Working
It may also be the On-Body Detection is set to ON under the Smart Lock feature

The way I fixed mine after reading all of these posts was Settings>Lock Screen and Security>Secure Lock Settings>(Enter Pin or whatever security option you have enabled)>Secured Lock Time>, then add the diode to the first selection, "Instantly with the power key or when the screen times out." Then it prompted my security feature everytime the phone locked. When adding a timeout period if you lock with the lock button for some reason it thinks you did it by choice (owner) and figures you will open it without the need to input security feature. I have everything mentioned above off so, I was baffled as to why it didn't prompt my pin option. Now timeout or self lock (by owner) it prompts pin all the time. Hope this helps.

Note 8
Mine has the same issue. but i dont have any trusted devices. i think its a bug in the software. It only asks for pin or iris scan after a couple of minutes being locked otherwise i can just swipe and it unlocks which is ****.

Don't do hard resets, login to the samsung account, go to find my mobile, then unlock your phone from there, it will delete the password. It will tell you to use a pin for access to samsung and the phone etc. Add the pin into the phone, then unlock the phone when you're on the phone screen. This will wipe off the passcode, this is so your settings don't keep restarting (happened to my note 8). Next part is to clear credentials in the settings and reset settings. None your data, apps will be affected, just the theme and basic security stuff. Now you can finally reset your pattern to however to you want it to be. As good as gold! Hope this helps.

Thanks a lot. I finally figured out what the issue was. My On-Body-Detection in the Smart Lock settings was On.

Just go to Setting -->Lock Screen and Security --> Smart Lock. Deactivate all the options there.

I have a Moto E4 and I have a secondary pattern up and everytime I swipe up it unlocks it instead of making me put in the pattern

Can G5 plus Fingerprint unlock without pw/pin/pattern lock?

Generally, I've never used a pin/pw/pattern to unlock my phone. Wise or not, I like to get quick access often.
The G5 Plus is my first phone with a fingerprint reader. I thought that would help me get better security without slowing down access.
However, I can't find any way to enable fingerprint access without first entering a PIN, password, or pattern lock! Online tutorials say there should be a "None" option on that screen, but mine doesn't have any such option.
I don't see how this makes any sense:
- You can have no PW/PIN/Pattern and no Fingerprint
- You can have Fingerprint, but only if you have PW/PIN/Pattern to access Fingerprint. This seems to defeat 95% of the utility of having Fingerprint! (the other 5% being when you need to validate Google Pay or whatever)
It seems like having an in-between option (fingerprint only) would be more secure than nothing, so why isn't it an option?
Is there any way to have fingerprint access without having to unlock first?

You need to have a password as backup. You only have to enter that password once after setting up the fingerprint, and on first boot. After that it does not requires the pin

Also, many custom ROMs have an option to unlock with FP without unlocking it with pin/pattern at all

When you use the fingerprint sensor, it bypasses the password and unlocks the device instantly. Password is a backup in case the sensor malfunctions.

It also asks you for your password once every few days.

help! my phone is locked and i can't open it

I added pin lock because the gmail ask for more security or something like that.
i don't know why but i can't get access to the phone - my number doesn't fit and i have no idea what to do.
i don't want to loss all my data, this is non-root device.
anyone can help me please?

Unless you setup smart lock where it unlocks when you're at your home wifi for example. There isn't much you can do with a lost code and a device with a locked bootloader. I would try to do your pin but try the possible buttons you could have accidently pressed. Other than that you would need to boot into recovery and just factory reset. This will get your phone back but your data will be wiped. Maybe someone else has suggestions. Did you enable USB debugging?

Yeah unless you have smart lock, usb debugging, and/or you are rooted you are going to have to loose your data

I always enable smart lock for my car, for just this very scenario.
I once was using "ultimate rotation control" and due to a bug, it would blank the lock screen (the phone didn't have FP reader, at the time) so that it was impossible to unlock. But then I remembered I had it set up to automatically unlock in the car. Lo and behold, the solution worked.

Can't you use the Find My Android thing that Google has to change the passcode on your phone? I'm pretty sure you can use it to remotely lock your phone. Then to unlock it you use your Google Password.

unlock with "OK Google" if you have Voice match activated?
