The official Android client for app.keyspace.cloud. A beautiful and secure password manager where you hold the keys.
Create and store passwords, two-factor authentication codes, backup codes and more.
Secure notes with rich previews and markdown support
Access your credit and debit cards with ease
Swipe up and scan a QR code to instantly log into your desktop
All of this is backed up and encrypted with a 12 word recovery phrase.
Zero knowledge Encryption
Keyspace uses end-to-end encryption to secure all user data (Logins, Notes, Cards etc.) with keys derived from a 12 word mnemonic seed phrase.
Signature based authentication scheme
Most password managers transmit a hash of users master password for authentication purposes. Bitwarden – See page 9 Keyspace uses a challenge-response based authentication scheme to eliminate users master password hashes being stored on the backend. The client simply signs cryptographic challenge and sends it to the backend. Password hashes never cross the wire.
Deterministic Key derivation
Most cloud based password managers derive a master key that encrypts other keys which are ‘wrapped’ or ‘protected’ which is then stored on their servers. Keyspace derives all keys deterministically on your device from the 12 word mnemonic seed phrase eliminating the need for ‘wrapped’ keys.

Stronger and faster cryptography
Strongbox-backed Android Keystore
Your encryption key is stored on a separate hardware security module (HSM) inside your phone which has its own CPU, storage and RNG, safeguarded against key extraction. Keys are only accessible upon successful device authentication.
Instantly sign out and delete all on-device Keyspace data by tapping a single tile. Useful if the country you’re in countries has a poor human rights record or if your device is confiscated without your consent.
On a flight? No problem. Keyspace can do everything offline and sync once you’re online.
Native android app
Keyspace is written in Kotlin. Keyspace is designed to be fast and lightweight in size <20MB.
Note: Strongbox-backing depends on availability of device-specific hardware. Keyspace will use other secure methods in case your device has no Strongbox.
