This is a demo. There are no real codes here.

01

A place for every code

Service, account, note and a list of codes. Copy the code you need, then mark it as used after signing in successfully.

02

Encrypted on your device

Contents are protected with AES-256-GCM. Your master password unlocks the vault. Auto-lock activates after two minutes of inactivity.

03

A backup you can take with you

Export a .reserve369 file and move it to another phone or the web app. Open it with that backup’s password or recovery key.

RECOVERY

Save first. Recover later.

A new device needs two things: a backup file and its password or recovery key. The key alone does not contain your codes.

  1. 01

    Create your vault

    Choose a password of at least 12 characters. Save your separate recovery key and confirm it in the app.

  2. 02

    Add your codes

    Copy backup codes from Google or another service’s settings. The app stores codes already issued by that service.

  3. 03

    Save a backup file

    Export the encrypted file after changes. Keep a copy away from your phone and keep the key separate from the file.

  4. 04

    Open on a new device

    Select the .reserve369 file and enter its password or recovery key. Then choose a new password and save the new key.
