Show live TOTP 2FA codes instantly from a user-provided secret. # 2FA Live Open-source browser extension for showing a TOTP 2FA code instantly from a shared secret. ## Features - Generates 6-digit TOTP codes locally in the popup. - Updates automatically when the current code expires. - Shows the countdown to the next code. - Copies the current code with one click. - Does not send secrets anywhere. ## Secret Format Paste the Base32 secret provided by your service, usually from an authenticator setup screen. Spaces are ignored. You can also paste an `otpauth://totp/...` URL. 2FA Live extracts the `secret` value and uses the URL's `period` value when present. ## Author Trang Ha Viet ## Source code https://github.com/tranghaviet/2fa-live
