- Password health — find weak, reused, and exposed passwords
- Portable backups — export and restore with PeachScript or a
.peachfile
Peach Pro adds:
- Peach Sync — end-to-end encrypted sync across paired devices
- Passkeys — save and use passkeys in Chrome and Firefox
- Peach Codex — print an encrypted, scannable backup of your vault
- Advanced vault health, Canary Entries, and duress tools
See the Peach website for current availability and Pro details.
Install
Open Source
Peach is released under the GPL v3. This repository contains Peach's Chrome and Firefox browser extensions. Android is maintained separately.
The source is hosted on Kepr, Asha Software's version control platform.
Security
Vault data is encrypted with AES-256-GCM and protected by Argon2id key derivation. Peach Sync authenticates paired devices and encrypts data in transit.
Implementation details live alongside the code:
Building
