What problem are you solving?
Part of: #3335
What approach did you choose and why?
Currently, if a user enters the wrong totp code during mfa verification, they'll be redirected back to the sign in page. This PR would do the same with webauthn.
This would solve #3335 as the sign in flow would be reset and the correct session variables will be set when the user is prompted again. A reason I decided to redirect back to sign in instead of re-rendering the prompt page is that another error that could occur is that their login session is expired. It wouldn't make sense to re-render the prompt page as auth would always fail (the login session is expired).
Next steps
Will need to revisit the same for email confirmations, multifactor auth level update and password reset.
