I want to be able to disable lock screen security based on certain conditions. Right now, I'm using Llama and the "change screen lock password" function. That can disable whatever lock screen security I have, but only re-enable PIN security. Any way to turn knock code off, then set it it to turn back on automatically?

any solution yet? :/
I was using NFC LockScreenOff Enabler on my Nexus 5 until the screen hardware died on me. Google is currently sending me a new one. I was MultiROM'ing Lollipop and tried the smart NFC unlock feature, but I didn't like it because you had to turn the screen on, hold the NFC tag, and swipe a swipe-to-unlock screen.
I have an NFC implant so i want the functionality just like NFC LockScreenOff Enabler. NFC polling with screen off, hold phone up to my hand, phone unlocks straight to home screen.
Is there a working solution for lollipop?

not currently, however there are several non stock lock screens that have this feature such as:
Tap Unlock or Uber Device lock

They're both ugly and not reliable, IMO. I couldn't even get Uber to work and sent the dev an email. He was a ****ing jerk and basically said I'm dumb and didn't enable the app. Come on.
I wonder if there's a way to use Tasker to bypass the swipe screen after touching the phone to NFC. I don't mind placing the phone on my implant and pressing the power button. Having to then swipe another screen requires weird hand acrobatics when using an implant, which is why I'm still on 4.4.4.

using the secure settings and locale plugins it is possible to make a profile that disables lock screen on a specific nfc tag read and then reanables lockscreen when the screen goes off

Not going to work. NFC polling in stock Lollipop is Screen On, Unlocked. We need to enable alternate polling modes to even be able to read the NFC tag. Go ahead and try it, your phone won't even read your NFC tag, let alone disengage the keyguard. Even if you got rid of the keyguard, you still have the Pattern Unlock, or PIN, or password. You need Secure Settings plugin within Tasker to remove those.
The only ROM for the Nexus 5 at the moment with different NFC polling options is Cataclysm. I tried extracting the NfcNci.apk after I changed the settings, but the settings didn't stick around when I brought it to stock ROM. I'm guessing you have to go in and manually add the settings or change the polling code within the apk, but I don't know how to decompile and edit code.
If you know how to do that, that's all we need; a modified NfcNci.apk with Screen Off, Locked polling mode. It's located in system/app.
Your guide is useless as it stands, just being honest.

The tasker profile above worked fine with a pattern set, scan the tag the lockscreen disapears till you turn off your screen, I tested it with secure settings and could see no benefit to also having it disable you password etc as the lack of keyguard meant you were never prompted for it
but aye a different polling method is needed

Aye, have requested the thread be removed as it'll only work with nfc lockscreenoff... and that in itself removes the need for this
thanks for the heads up, rookie error on my part there

All good. We just need someone who knows what's up to modify NfcNci.apk for us. I just started the semester and can't devote time to it right now.

Even if it has been a while, this might be useful:

There is also a step-by-step guide on how to mod it yourself, a few pages later, and a guide for NFC with screen on but locked. I tried it on 5.1 (Xperia S, nAOSP), worked like a charm.
Is it possible to turn NFC ON/OFF? Where? It doesn´t work for pairing with my phone which has NFC and on phone is NFC working correctly.....
Thank you for information.
Wear does not yet support nfc, so unless you write it into the kernel, it is disabled... for now.
Hello all,
I'd like to use the fingerprint to lock only specific apps without having a lock screen active.
With other smartphones I can do it, with the P2 seems to be impossible.
In order to activate the fingerprint security, I have to record some fingerprints and that's ok. Then I select the single apps I want to lock.
But, if I disable a lock screen the digits scans are deleted, therefore the fingerprint app lock feature stops working.
In other phones when I disable the lock screen, the app lock function keeps working (fingerprints scans are not deleted).
Is there any workaround ?
I only manager to get partial workaround - I set option that the phone will lock itself after 30 min and I used simple PIN to use it quickly if needed and also I use smart lock so it will not lock that often...
I tried using Smart Lock with a NFC tag as a Trusted Device. I'm assuming nothing has to be written to the tag, it just goes by the tag's ID. The tag is accepted during setup, but doesn't unlock the device. While the device is locked, the phone makes a noise signaling a tag has been scanned.
I also tried this method, but it seems Secure Settings's ability to change the pass/pin has been broken since Android 5.0+.

I set up a test with the same "trusted" tag. I set it up so when the tag is scanned, it will turn on the flashlight using Automate.(like Tasker).
The tag does work to start the flashlight, but not while the device is locked. Maybe despite Smart Lock being enabled, the lockscreen is not allowing tags to be processed when scanned.
