Bug ID: 357954 Summary: Sometimes get "unlocking failed" error when using yubikey with static password Product: kscreenlocker Version: 5.5.1 Platform: Other OS: Linux Status: UNCONFIRMED Severity: minor Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: cnm...@ruggedinbox.com CC: bhus...@gmail.com, mgraess...@kde.org While testing a Yubikey configured with a static password (press a button and the password is automatically typed) over 55 characters, I found that a unlocking the lock screen fails about 50% of the time (10 failures in 20 attempts). This appears to be due to the Yubikey entering characters very quickly (over 55 characters in 1 second) that some characters in the password are not typed into the field. This has never happened when entering the password from the desktop or when logging in for the first time after a reboot. If I copy the password when on the desktop, lock the screen, and paste it into the password field, it never fails. If I hit Enter after getting an "unlocking failed" error without clearing the field and entering it again, it always fails. While testing, I noticed that this seems to happen in streaks - with it failing multiple times in a row, then it being ok for several attempts in a row. Here's the pattern for 20 trials: 2 successful 4 failures 4 successful 3 failures 4 successful 3 failures Reproducible: Sometimes Steps to Reproduce: 1. Lock the desktop 2. Use a Yubikey or (maybe) something else that quickly enters a long password to log back in https://en.wikipedia.org/wiki/YubiKey -- You are receiving this mail because: You are watching all bug changes.
