Fistbump & Whisper

Your two-factor codes, and your passwords. Two apps, on every device you own, encrypted so that only you can read them.

Why two apps and not one

Because one unlock should not open both.
A second factor exists so that somebody who has your password still cannot get in. Keep the password and the code in one vault behind one sign-in and you have quietly undone that. Fistbump and Whisper have separate vaults, separate passkeys and separate sign-ins — you sign into each.
They still feel like one thing.
The browser companion fills a password from Whisper and a code from Fistbump in the same flow. It never holds your vault; it asks the apps you have already unlocked.
We cannot read either of them.
Everything is encrypted on your device before it is stored. Our servers hold a blob they have no key for, and there is no code path that would accept one — not a promise about what we would do, a fact about what we can do.
