TOTP Generator from Secret Key Online: practical answers

What secret format does a TOTP generator use?

Most services provide an RFC 4648 Base32 secret containing letters A to Z and digits 2 to 7. Spaces and lowercase formatting can usually be normalized before calculation.

Why does my TOTP code differ from my app?

Check the device clock, secret characters, algorithm, digit count, and time period. The standard setup is SHA-1, 6 digits, and a 30-second period.
