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 5.1.1, which restored issuer-only tokens, a database containing a token with neither an account name nor an issuer still refused to open, and a single such token blocked every other token from loading. These anonymous tokens, common in databases created before 5.1.0 added load-time validation, now load with a synthesized placeholder label instead of being rejected.
