TOTP Manager
An all-in-one testing solution for developers implementing TOTP systems into their software.
TOTP Manager can be used to generate TOTP configurations of all shapes and sizes, as well as generate the codes to use in your software to log in. While most of the TOTP apps only support SHA-1 hashing, 30 seconds time intervals, and 6-digit codes, TOTP Manager allows you to configure all the possibilities found in the TOTP IETF standard.
