Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Confirm email Choose confirm email when the service must prove that the user can access the mailbox for account activation, recovery, sensitive notifications, invitation acceptance, or a verified contact route. The confirmation page states which email address is pending and why access to that mailbox is required. MDN documents one-time-code autocomplete for short-lived code entry when a confirmation code is used.
Confirm phone Choose confirm phone when the product must prove that the user can receive a time-limited text-message or voice code at an already captured number. The confirmation page states why phone access is required, what channel was used, and what phone number is being confirmed when disclosure is safe. MDN documents one-time-code as an autocomplete token for short-lived code entry.
Sign in Choose sign in when the user needs to start or restore an authenticated session for an existing account. The sign-in form identifies the protected service or destination before requesting credentials. MDN documents username, current-password, new-password, and one-time-code autocomplete purposes.
Two-factor authentication Choose two-factor authentication when the user must satisfy an additional factor after a primary credential, SSO return, passkey flow, risk signal, new device, or sensitive action. The challenge appears only when the server requires additional verification and the protected action remains blocked until success. MDN documents one-time-code autocomplete for additional-factor code entry.
