DevAuth

DevAuth — The Authenticator for Developers and Tinkerers DevAuth is an authenticator app made for developers and standard users alike. If you're a standard user, you can use the app normally, just like any other authenticator. Scan a QR code or enter a setup key and you're good to go. If you like to tinker around, DevAuth allows you to do some interesting stuff, such as changing the length of your code, changing how long it's valid, or even choosing the algorithm (SHA-1, SHA-256, or SHA-512). Normal users can simply ignore the extra options. DevAuth works fully offline. No account required. No cloud. Your codes never leave your device. Notice: Tinkering features are not supported by every platform. Only enable them if you know what you're doing and if you know your platform supports it.
