Why Client-Side 2FA Matters
Your TOTP secrets should never leave your device. Here's why 2fas Plus keeps every byte local.
Most authenticator apps sync your seeds through a server. That server becomes a single point of failure — one breach exposes every user's second factor. 2fas Plus takes a different route: your setup keys are generated, stored, and consumed entirely inside your browser. Nothing leaves the tab.
This has real consequences. You can audit the network panel and see zero outbound traffic when a code is generated. Backups are opt-in files that you control. There is no account to compromise because there is no account at all.
Client-side security is not just a marketing line — it is the only architecture that gives you provable custody of your own second factor.
