Frequently Asked Questions
Why are some 2FA secret keys 16 characters and others 32 characters?
16-character Base32 keys (80-bit) follow older Google Authenticator conventions, while 32-character keys (160-bit, like DJQE4DWM...) follow modern RFC 6238 standards used by Epic Games, Facebook, and GitHub. Both work identically here.
Where are my saved 2FA keys stored?
All keys are stored strictly in your browser's localStorage. Nothing is ever uploaded to any server. Temporary keys expire 7 days after creation unless switched to Permanent.
