It would be interesting to have a separate field where you can mention if the account uses another type of two-step login, such as SMS, email, hardware key, etc, and be able to specify the phone number or email address used, or the hardware key type or reference.
This would also have a positive impact the “Inactive two-step login” report which returns a lot of false positives as Bitwarden is not aware if an account uses another type of 2FA.
