Authenticator not supported

authenticator.unsupported · HTTP 400

What it means

The enrolment asks for something Waridex's authenticator does not do: a counter-based (HOTP) secret, an algorithm other than SHA1, SHA256 or SHA512, a code of other than 6 or 8 digits, or a period other than 30 or 60 seconds. The problem's parameter field names which.

What to do

Check the app's MFA settings for a TOTP option with supported parameters. Nothing is guessed, so a value outside the set is refused rather than rounded.

Every error the API returns is a JSON problem (RFC 9457) whose code names it and whose type links to its page here. See the docs for how the API works.
