Using fingerprint Lock for just apps

Hello
Is it possible on the Nexus 6p to use the finger print scanner to unlock apps with the finger print scanner on the phone without using it to lock the phone and having to setup the PIN lock?
If you mean that you'd like to have an app that locks certain apps and unlock it with the fingerprint scanner, you should try FingerSecurity. You can set which apps are locked by the app and you can then use the fingerprint scanner to unlock them.

You can join the Beta to get Nexus 6P support. Works great.
and without any app?
just using the F.P to wake the screen up or lock it?

I don't understand what are you saying.
With Nexus 6P you just have to touch the fingerprint sensor without touching any button and the screen will wake.
Android doesn't have a functionality to put a fingerprint lock to open a certain app. For that you will have to use the link above.
i wish, but

in order to activate FP, it demands another locking feature.

Yes and that is how it works with every device ever.
No device will allow you to have only fingerprint security (if you mean that you want to make it impossible to unlock your phone without your f.p) because modern (6.0+) Android phones would be thrown into the garbage if your f.p. sensor stops working properly. (the system encryption will be fu*ked cause it requires a pin)

It says: fp with linw/password/code.
No option for "just" fp.
Android 7.1.1
Just like what was said above, there is no option for just fingerprint. You need to have a backup way of unlocking your device. So if you get your fingers chopped off, fingerprint sensor fails, etc. you could still unlock your phone with a pin/password/pattern.

so what mihovil13 said:
"With Nexus 6P you just have to touch the fingerprint sensor without touching any button and the screen will wake"
is not correct?
just the FP isn't enough
oh! finally i got it.
forget the last question. everything's great

Fingerprint Unlock not enough - OOS 3.0.2 requires pin when locked unconventionally

So I just upgraded to the OOS 3.0.2 MM build, and there's a new issue that's greatly annoying me. If you lock the phone with the power button, the fingerprint scanner will unlock it fine. However, if you lock it with something else (as I do with both shake-to-lock and Nova's lock actions), it will insist on ALSO asking for the pin/pattern unlock once your fingerprint has been scanned.
Anyone find a way to disable this security feature while still having a fingerprint unlock in place? Neither Gravity Box nor the security settings are presenting any obvious options
That's a feature of Android MM, not OOS. It can't be disabled.

There is no way to disable it? Even rooted? No xposed or system level hack?
It seems to be an error in design of Nova launcher and other solutions. They don't use the correct way of locking the phone hardlocking instead of softlocking, and therefore the phone will ask for pin just as if you restarted your phone.

I had same issue when i used double tap to sleep in nova launcher prime.... i is because it uses device administrator to lock phone! I fixed by using root to lock my mobile....
Long story short you need your application to use root to lock your device!
But what if the shakelock app I use (and love!) doesn't use root....? It's sounding like I'm out of luck here. How have you managed to make Nova use root to lock?
I guess I'm more of an Apex guy, don't fancy Nova launcher even though I bought it a couple of years ago. I just double tap on top part of screen to lock, or press the power button, or let it timeout. For unlocking, I just use fingerprint, no fuss, no asking for code.
I was happy with Nova Launcher (which is currently on sale for $0.99 on the Play store), until I found out that it has a bug in voice searches from the Home Screen's search bar. It annoyed the heck out of me as it kept on complaining "App not installed" when clicking on the little mic. I had to click on the search bar and THEN click on the other mic that appeared, inorder to access voice search. Defeats the purpose of the voice search b/c I use it a lot while driving and I cant be bothered to be clicking through so many hoops. So I switched my homescreen launcher to Google Now Launcher, while keeping everything else Nova Prime.
For anyone interested, I have found a sort-of solution. Using a combo of Xposed Maxlock and Lockscreen Disabler, it's possible to have a lockscreen up that you can dismiss by using the fingerprint sensor. There's a fairly obvious downside in that it doesn't matter what fingerprint hits the sensor, as anything at all unlocks the screen (which is Lockscreen Disabler's function) but it works as a way to use a non-root lock method that still allows you to unlock the screen with just a touch. Until such a time as someone finds a better solution
I'm pretty sure that it's easy to write a simple apk that uses the root method to call the screen off function. Only if someone would write that
Why I tell that - because if You double tap the status bar - the screen locks and You can easily unlock it just with the fingerprint sensor... therefore, that function does exist already in the ROM.
Yeah, I've got the Nova rooted lock function working, so those actions or GravtiyBox stuff like double tap status bar will work and not require pin+fingerprint, but my specific ask is this way to lock the screen by quickly flicking/shaking the phone (which is GREAT and I don't understand what hasn't been included in stock) - none of those seem to use root to lock so this workaround is a way to have that convenient screen off + convenient fingerprint on.

"device administrator locked device" when unlocking with fingerprint

First my fingerprint scanner works perfectly 10 out of 10 times it recognizes my finger,
but sometimes the lock screen take me straight to pattern lock and the message "device administrator locked device" appears on the screen.
why it is happening and what is the meaning of that?
Do you use an exchange account on it? if so, it is possible that adminstrator policies from that are nor considering the Fingerprint a viable security for the phone. Or it may force the pattern after a certain amount of time

No.. I don't use an exchange account, thanks.
Are you using the FingerPrint Quick Action app? What are your current Device Administrators, knowing what devices are permitted to lock your screen as an Administrator will help you identify the culprit.

I don't use FingerPrint Quick Action app..
I attached a screenshot of my Device Administrators..
I have disabled them for now to see if it was the cause of the problem.

screen off and lock is the culprit, any device administrator that locks your screen will require a pin to unlock regardless of fingerprints or smartlock configuration.

The app in question needs to turn the screen off via root. The fingerprint quick action app does just this.
why do you need an app to turn off screen? is your power button dead?

I just want to replace the home button long press from google now (or now on tap) to turn the screen off..
I did it with the "Screen off and lock" app but it caused the pattern lock "issue".
Nova Launcher will allow you to do a double tap to lock the screen. It will either lock it without use of fingerprint or it will set up a black screen and time out to use your device security or it has a root abilities to lock your device and use device security.

Power goggle is great and the only problem is the same screenlock problem as you described.

Strange
This is intended behavior on android 7+. Tested on Galaxy S5 with 7.1 Linage, Huawai Mediapad M3 and Galaxy S8+
However there is an app for samsung edge ( not sure if all edgy phones, tested on s8+ ) that can lock the screen without using device administrator. The app in question is Softkey Edge for Edge Panel, installed from galaxy app store. It allows the phone to be unlocked from fingerprint, without pin or pattern as nova prime screen lock gesture for example. And without root.
So there is a way to lock screens without device administrator, we just need to find it.
It's strange. I did not have this problem ever. I had to reload my phone because Oreo update blew up some programs I use a lot. So I downgraded, and now I have this problem.
I don't see anything in my Device Administrators that would cause this. And I haven't added any new programs for quite a while.
i have the same problem .after i unistalled screen off and lock application ,after working fine.

I presume that is a third party app. I don't have that to uninstall.
I found that the app "Files", a Huawei system app, giving this problem when marked as a device administrator. Disabling it's device administrator privileges solved the problem for me. Who would have thought Huawei's own app gave this problem.
I now lock my screen using Greenify's Sleep & Hibernate action, set up to be activated with a double-tap under Nova Launcher's gestures settings. No problem waking up and using fingerprint. Of course, Greenify must not be a device administrator as well. There are other ways to shut down the screen if not using Greenify.

Idiotic fingerprint storage system.....

Hello,
Guys, i would really appreciate some help with this.
I have a Zenfone 3 5.2' and i am trying to use an AppLock that will work with my fingerprint.
Asus Zenfone 3 has a completely idiotic design in how it stores fingerprints, i can not have a fingerprint stored on the device UNLESS i use a lockscreen that is protected by either fingerpring + pin or pattern, there is no way to have a fingerprint stored on the device if i don't have my lockscreen protected, i cant just use swipe to unlock and have a fingerprint stored.
Any stored fingerprints will get deleted if i dont use pin or pattern lockscreen.
My question is.....how can i disable my lockscreen or preferably keep it on swipe to unlock but still have a fingerprint stored so that i can use AppLock to lock certain apps and be able to unlock them with my fingerprint ?
Any help will be greatly appreciated.
settings - security - clear credentials

And this will help me how exactly...?
What i need is to have a fingerprint stored on the device without having it (or pin / pattern) protecting my lockscreen.
Is there no workaround to be able to use the fingerprint for unlocking apps ? Can anyone think of something ? some separate way to store the fingerprint, in the app itself or so would be nice.

Any way to keep fingerprints without Lockscreen?

I'd like to keep fingerprints to use with App Lock and such but without using the lockscreen. Any way to keep them?
I also want this, so it works like a password for apps
but I don't like to unlock my phone at all, just swipe on the lockscreen
I searched a lot, found another thread someone wanted this too
but nobody understood him, they thought he wants only Fingerprint without pin?
but why is it not possible to use Fingerprint (and backup pin or password) ONLY for applock, and not on the lockscreen

In addition to the FP, use on body detection and face unlock.
That should reduce if not eliminate the need to unlock the phone manually.

But then I can't swipe on the lockscreen, there's no lock at all, so if I was previously in whatsapp I would be instantly online, instead of just reading messages on the lockscreen

Try using the app No Lock :
https://play.google.com/store/apps/details?id=org.jraf.android.nolock&hl=en_US
I don't use the FPR,or,any lockscreen for that matter,so,IDK if this will work.
I used it on other phones where you had to use at minimum a swipe to open & it bypassed that requirement,perhaps it'll do the same in this situation.

It was only a suggestion.
I don't mind a lock screen on my phone.
I want my phone to lock.

Thanks for the suggestion. Tried it, but still have to swipe to get in. I'm not sure of other OS' but TouchWiz allowed for it. I'll write OnePlus Dev's to hopefully include it on an update. Also, native rear flash notification since we don't have a led for it.
