Tips for a Faster Response

For Bug Reports

Include your browser name and version, the tool you were using, what you expected to happen, and what actually happened. A screenshot helps enormously. The more detail you provide, the faster we can reproduce and fix the issue.

For Tool Suggestions

Tell us what the tool should do, who would benefit from it, and why it fits a privacy-first, browser-based approach. We prioritise tools that keep user data entirely on the client side with no server-side processing.

For Privacy Concerns

2FA Fast processes all data in your browser your secrets, passwords, and hashes never leave your device. If you have a security concern or have found a vulnerability, please describe it clearly and we will respond with priority.

For General Questions

You may find a quick answer in our FAQ page or our blog. We cover topics like how TOTP works, how to set up 2FA, what to do if you lose your authenticator device, and more.
