Fingerprint not working: javax.crypto.IllegalBlockSizeException

edited August 13 in Android

Hi,

I had my 1Password app configured so that I can open my vault using my fingerprint. It has been working smoothly for a long time. But today I open the app and it tells me I cannot use the fingerprint to open the vault. Then I enter my master password. And when I go and try to re-enable the fingerprint feature I have the following stacktrace:

javax.crypto.IllegalBlockSizeException

android.security.keystore.AndroidKeyStoreCipherSpiBase.engineDoFinal(AndroidKeyStoreCipherSpiBase.java:519
...
com.agilebits.onepassword.mgr.BiometricAuthMgr$1.onFingerprintAuthenticated(BiometricAuthMgr.java:225))

(This is not the complete stacktrace, as I was unable to take a screenshot or select the text of the dialog. I reproduce the first and last method calls by hand.)

Best regards

PS :

Running Android 7.0 and 1Password indicated as up-to-date by Google Play.


1Password Version: 7.6.2
Extension Version: N/A
OS Version: Android 7.0
Sync Type: N/A

    Plus, when I open the vault using my master password it says “the master password has been modified” as a gray popup on the bottom of the UI that disappears by itself.

    After a reboot, I am able to re-enable the fingerprint feature and there is no more stacktrace.

    Hi @N_Z_L!

    Thank you for the update! Have you managed to reproduce this again even after a reboot?

  • I actually am also having this problem on my cell phone. The bio works on my tablet with no trouble, but I receive the above error on my Android phone. I have rebooted, uninstalled and reinstalled the app, with the same outcome. Any guidance would be appreciated!

    Hi @dpgaspar Can you please disable your Biometric Unlock settings on the device, then re-enable them? Once you've done that, are you able to turn Biometric Unlock on for 1Password?

  • I use a customized Samsung galaxy s7 edge and I'm having trouble with the app downloaded from Play Store. I can't enable the fingerprint unlock option and I can get an error message just like the guys mentioned above. I am willing to reproduce the problem at any time (UTC+8) and I can also offer you the error message. Looking forward to get a response.

    Hi @Leo_Maxwell. Can you clarify what you mean by a customized Samsung Galaxy S7 Edge? Are you using a custom ROM on the device, or is it rooted?

    We have noticed that some custom ROMs change the OS in such a way that we're not able to workaround this error.

  • Well it's now running Pixel Experience and you can see it obviously that this ROM is just like its name, a pixel-like ROM. Rooted. It's based on AOSP without many changes and I'm quite sure it won't change such a critical system behavior. I believe it's a 1Password app problem and I can see similar posts complaining this problem on Samsung models. As a geek myself, I wonder if this problem is related to Samsung things. Thank you for your work for our users.

    @Leo_Maxwell Did you try the steps mentioned earlier in the thread, such as disabling biometric unlock on the device, uninstalling 1Password, re-enabling biometric unlocking and adding your fingerprints, and reinstalling 1Password?

  • I already tried to re-enable biometric unlock in the Settings and re-configure my fingerprints and neither worked. I didn't try re-install the 1Password because it's kind of complicated to configure my account in a brand new app. But I'm more than willing to try it if necessary. Looking forward to having your response.

    Hi @Leo_Maxwell!

    Let's try refreshing your phone and 1Password settings a little differently before reinstalling if it's easier for you. Make sure you have your Master Password for 1Password before attempting this.

    1. Disable fingerprint unlock in 1Password on your Android device
    2. Delete your saved fingerprints and disable fingerprint unlock in your phone settings
    3. Restart your phone
    4. Reenable fingerprint unlock in your phone settings
    5. Save your fingerprints again
    6. Reenable fingerprint unlock in 1Password

    Let us know how this works for you. :)

  • I'm having this same issue along with many more as i have never used an android in my llife until now...
