Re: PIN after Fingerprint Unlock

It will ask me for a PIN once-an-hour, regardless of my smart lock settings.

It will ask me for a PIN once-an-hour, regardless of my smart lock settings.

There were some issues with different launchers and lockscreen apps that I was reading about in other threads. Idk if that can be an issue.

Re: PIN after Fingerprint Unlock

If it doesn't feel like unlocking with my fingerprint, this closed padlock will appear at the bottom of my screen.

My phone will unlock if use lock icon is replaced with an unlocked padlock, fingerprint, or face.

Re: PIN after Fingerprint Unlock

My lock screen app always makes me enter my pattern after the fingerprint wakes the phone. Very handy if I want it locked as I have a Smartwatch as a trusted device.

I use smart lock and do not have a lock screen app. I'm still prompted for my PIN when I see that locked padlock at the bottom of the screen.

Could be forced by a corporate mdm solution, assuming you use your 6P as a work phone. That's the only thing I can think of.

Thank you everyone for your help. I'm still in search of a solution. I will update this thread when I find one.

Re: PIN after Fingerprint Unlock

I use the scanner to unlock and it opens up no worries. Though I setup the swipe pattern as the back up as well if I unlock via power button. When the pin was setup that would come after fingerprint. So I changed to swipe. Now opens up straight away. Weird.

I was thinking the same thing, are you tied to some exchange account?

I think I know what's happening. It was happening to me. I was using the trick with nova launcher and another app to be able to lock my screen by double tapping it. After I did away with it the behavior stopped. I've gone an entire week without rebooting my phone and in that time not once was I asked for pin. Now pin is only required after reboot, as it should be.

Thanks a lot dude, that seems to fix the problem.
Just remove the double tap to sleep in Nova settings and magically everything will be normal. It's because nova is in use as device admin and OS thinks it's a security breach , cool security by Marshmallow!

Re: PIN after Fingerprint Unlock

I turned off System Administrator privileges for 'Dynamic Notifications' (to turn off the screen after a notification) and updated to 6.0.1. I'm not sure which made the difference, but I haven't had any problems since.

Re: PIN after Fingerprint Unlock

I had the same problem so I disabled it then set it back up. I remember there being a question asking to use the pin after unlock try selecting no. I'm good to go now

Unlock using your backup screen lock method

Sometimes you might need to use your backup PIN, pattern, or password:

When your fingerprint isn't recognized after a few tries
After restarting your device
After switching to a different user on the device
After more than 48 hours have passed since you last unlocked using your backup method

https://support.google.com/nexus/answer/6285273

That's funny that Google's Nexus Help doc says 48 hours, when the source code seems to indicate 72 hours:

/**
     * Milliseconds after unlocking with fingerprint times out, i.e. the user has to use a
     * strong auth method like password, PIN or pattern.
     */
    private static final long FINGERPRINT_UNLOCK_TIMEOUT_MS = 72 * 60 * 60 * 1000;

Re: PIN after Fingerprint Unlock

I turned System Administrator privileges for 'Dynamic Notifications' back on and the problem returned. The problem must be with this.

That padlock icon lets you lock the phone manually if smart lock is on. You shouldn't be pressing that unless you want to lock the device.

This is from help on the feature.

I'm just guessing here but I think it's simply a security feature. It will always ask for the PIN after fingerprint after a fresh reboot, and then will only ask occasionally after that when the phone is unlocked from screen-off (not rebooted). I see it roughly every few days.

Same here. No big deal for me.

This guy is exactly right. At least in my case. Double Tap to lock screen causes the pin to be put in over fingerprint scanner. Disable that feature and I no longer have that issue. Also, PayPal is currently having an issue to link prints both in the Samsung browser and app. Works everywhere else. This is with the Galaxy S7/Edge.

Mystery solved! If I don't use my PIN to unlock for 48 hours...it will make me. I've been trying to figure out the methodology for a while!

I noticed that when I get a Google app update that I'm forced to use my pin for extra security, and the only reason I noticed that pattern is because I had 2 beta releases a day a part and both times immediately after that one install I was prompted. And that's only been recent, and now that I think about it, previously it was only if I rebooted and it was once or hadn't used my pin in a couple days.
