Built around the moment you need a verification code

An authenticator should make the next step obvious

The ordinary task is simple: a legitimate website asks for a time-based verification code, and you need the right one before it expires. Guest 2FA Live is designed to put the current number, account context when available, and countdown in one browser view without first demanding a member registration. A person who manages several domain registrars, hosting accounts, infrastructure tools, or personal logins may benefit from viewing multiple time-based credentials at once.

That convenience does not change the security importance of a setup key. A long-lived seed should be handled with the caution you would apply to another authentication factor. The product's documentation explains which secrets are processed in-browser, how temporary data is cleared, and why the actual website remains responsible for checking every code.

Persistent member use adds a separate cryptographic layer

For a longer-lived collection, the member architecture pairs Google identity with a client-encrypted Vault. The browser is responsible for key handling, item decryption, code generation, and QR parsing, while the server authorizes member access and synchronizes encrypted records and revisions. Saved recovery material and encrypted backup give a path away from a single daily-use device when configured and independently tested.

The distinction between Google login and Vault unlock matters: identifying an account is not the same as possessing its decryption key. Feature descriptions reflect current source implementation; physical-browser performance, real Google callbacks, import compatibility on actual exports, and production operations have separate acceptance requirements. Readers should not confuse a documented design with a claim that every gate is already closed.

What 2FASync does not provide

2FASync concentrates on supported time-based OTP profiles and manual transfer QR imports. It does not promise native Android or iOS applications, a browser extension, full password management, team secret sharing, enterprise roles, HOTP Vault import, or automatic integration with Google's Authenticator cloud sync. It is also not intended to authenticate on behalf of the original websites; those services make the final acceptance decision.

Clear scope helps users avoid fragile workflows. If a required account uses a counter-based OTP or another unsupported profile, preserve its existing method. If you need organization-wide credential sharing, evaluate a tool designed for that policy model rather than assuming a personal encrypted authenticator Vault provides administrators, roles, and shared recovery.

Where to learn more before putting secrets in a browser

Start with how TOTP works, then review the supported profiles and QR security guide. For a permanent member collection, read the encryption, privacy, backup, and lost-device instructions before saving high-value accounts. These pages connect practical usage with what the code actually supports, including conditions under which an account cannot be recovered.

Information about an operating organization, verified contact inbox, or public response commitment must be confirmed independently of source functionality. Until those details exist, this page makes no claim about a company's legal address, awards, formal external audit, service uptime, commercial terms, or affiliation with Google.

Is 2FASync Google Authenticator?

No. 2FASync is a separate browser-first tool. Import from Google Authenticator uses a user-generated QR transfer; it is not Google's own in-app synchronization.

Does 2FASync include password management or shared team vaults?

No. 2FASync is a personal TOTP generator and encrypted member Vault, with no password manager or enterprise team-sharing capability.
