OTPClient is a secure and easy-to-use desktop client for TOTP and HOTP one-time passwords, built with GTK4 and libadwaita. Features:
Bug-fix release. Following the anonymous-token fix in 5.1.3, a database containing a token with an out-of-range digit count still refused to open, again locking users out of every other token. The load-time validator was stricter than the OTP engine and the app's own UI; the accepted ranges now match the engine (digits 4 to 10, period 1 to 120 seconds). Any token the engine still cannot use is set aside so the rest of the database opens, and is preserved for repair rather than dropped.
