PasswordPocket
Offline Credential Storage, Phone Auto-Fill, Travel, Privacy-Focused Users, Phishing Resistant Logins
Overview
PasswordPocket is a hardware password keeper the size of a small keychain tag: 36 x 48 x 6.5 mm, powered by one CR2032 coin cell, with no screen and no keyboard of its own. Credentials are entered, imported and managed in the Pocket app on iOS or Android, then stored encrypted inside the device, and the device pairs over Bluetooth 4.2 BLE so the phone can auto-fill usernames and passwords in apps and standard web forms. Atlancube, a Taiwanese company, rates it for around 1,000 logins plus encrypted notebooks, and it uses AES-256 with end-to-end encrypted transfer, PBKDF2 key derivation and a device master key that the vendor says it cannot recover. The device never touches the internet: there is no Wi-Fi, no USB data path and no cloud sync, so the entire attack surface is the Bluetooth link and the master key you choose. That is a real advantage over cloud password managers, but buyers should note the trade-offs honestly: the phone app is required for setup and management, the master key cannot be changed or recovered without a full reset, and Atlancube publishes no independent third-party security audit even though it documents its encryption design. It is best treated as a convenience-led offline vault rather than a certified cryptographic module.
Key Highlights
- Offline hardware password keeper that stores up to 1,000 logins in a 6.5 mm thick keychain sized device with no internet connection at all
- Bluetooth auto-fill for iPhone and Android detects login fields in apps and standard web forms so credentials never have to be typed or remembered
- AES-256 encryption with end-to-end encrypted transfer, PBKDF2 key derivation and a device master key that Atlancube itself cannot recover
- Encrypted backup and restore lets a full credential set be moved to a replacement unit, and browser logins can be imported from Chrome, Edge, Safari, 1Password, Bitwarden, LastPass and others
- Runs for roughly 6 to 12 months on a single user replaceable CR2032 coin cell, with a reset pinhole that wipes everything when needed
Technical Specifications
| Brand | Atlancube |
|---|---|
| Model | PasswordPocket |
| Storage Capacity | Up to 1,000 credential sets of login and password, plus encrypted notebooks for extra secrets such as bank account details |
| Security | AES-256 encryption with end-to-end encryption between the phone app and the device, PBKDF2 key derivation, a device master key and random security codes; credentials live only on the device and never in the cloud, and backups are encrypted with the same master key structure. Atlancube publishes its encryption approach, though no independent third-party security audit of the device is published. |
| Connectivity | Bluetooth 4.2 BLE to the paired phone, roughly 10 m unobstructed and about 4 m through obstacles, used for auto-fill; no internet, Wi-Fi or USB data connection, and only one device can be paired at a time |
| Display | No screen; a single LED indicator shows pairing mode, activity and reset status |
| Keyboard | No keyboard on the device; credentials are created, imported and edited in the Pocket app on iOS 14 and Android 12 or above, with a beta extension for Chrome and Edge on desktop |
| PIN Protection | A master key made of upper and lower case letters, numbers and symbols unlocks the device and every stored record; the master key cannot be recovered or changed without a full reset, and the reset pinhole under the battery cover erases all data permanently |
| Battery | User replaceable CR2032 coin cell, about half a year to a year in normal use; a plastic insulating tab has to be removed before first use |
| Memory Retention | Credentials are held in the device's own non-volatile storage and survive battery changes; encrypted backup and restore files can be exported and re-imported into the same or a replacement PasswordPocket |
| Dimensions | 36.0 x 48.0 x 6.5 mm (1.42 x 1.89 x 0.26 in) |
| Price | $52.99 |
