OTPfill

Meet OTPfill

OTPfill retrieves verification codes from connected email accounts when a user focuses a code field on their Mac. It displays the detected code below the field for a click or keyboard shortcut, and can fill it automatically when the sender matches the website. The app supports numeric and letter-based codes in browsers and native Mac applications.

Users can connect providers including Gmail, Outlook, iCloud Mail, Yahoo Mail, Fastmail, and other IMAP services. OTPfill checks recent messages while a verification field is active. Message text passes through its server to extract the code, and accounts can be removed in settings to revoke access. It is available as a downloadable macOS app.
