[quinqu]

What happened:

When adding an OTP device with tsh mfa add and try to enter the code, teleport says the code must be 6 digits long when the input surely is. The input is still not accepted.

Once created, enter an OTP code generated by the app: 624072
TOTP code must be exactly 6 digits long, try again
Once created, enter an OTP code generated by the app: 624072
TOTP code must be exactly 6 digits long, try again

Once created, enter an OTP code generated by the app: 426970

An error message if the input is incorrect/some other error message or for the input to be accepted.
