2FAS Pass Browser Extension

Use 2FAS Pass while browsing the Internet, with full control over the security at every stage.

The browser extension provides a next-gen password manager experience, where none of your Items are stored permanently in the browser's memory or on third-party servers. Instead, they are retrieved from your mobile phone when needed, and you control how each is accessed using integrated Security Tiers.

Once the connection is established, you can immediately use the Items assigned to the Secret Tier. Alternatively, additional confirmation is required to access Highly Secret Items.
