Two-factor codes & backup codes
Add a two-factor secret
When you turn on two-factor authentication, the website usually shows a QR code, often with a link like “Can’t scan it?” that reveals a secret (letters and digits).
Edit the account, paste the secret (or an otpauth:// link) into Two-factor secret and save. Vaultyn then shows the same 6-digit codes as your phone’s authenticator.
Use it on your phone too
In the account details, click QR code and scan it with Google Authenticator, Microsoft Authenticator or similar to get the same codes on your phone.
Backup codes
Sites usually give you a set of single-use backup (recovery) codes. Paste them into the account’s Backup codes, tick each one off as you use it, and always see how many are left.
Security questions
Some sites ask for security questions. Add Security questions to the account; the answers are encrypted just like passwords.
