Electronic Password Keeper
Offline Credential Storage, Wallet Backup, Travel, Seniors, No-Network Sites
Overview
The PIN-Master Electronic Password Keeper is the smallest and simplest device in this category: a credit card sized, 4 mm thin metal alloy slab that holds up to 150 password codes of as much as 60 characters each. You key a single master code into its twenty button keypad, read codes back on the four line LCD, and use the New, Edit and Erase keys to manage entries, all with no USB, Bluetooth, Wi-Fi or internet connection of any kind. The offline design removes the remote attack surface completely, and the device adds a useful failsafe in the other direction: if the master code is entered incorrectly four times, every stored code is erased so a lost keeper gives up nothing. It is deliberately low tech, which is exactly the appeal for a backup record or for people who want nothing to do with apps and cloud accounts. Be honest about the limits, though: the listing publishes no encryption standard, no algorithm detail and no independent audit, so protection rests on the master code and keeping the device physically safe, and at 150 entries with a manual keypad it is slower to use than a phone app or an offline keychain vault.
Key Highlights
- Wallet sized offline password keeper that stores 150 codes of up to 60 characters each in a metal alloy body measuring just 86 x 54 x 4 mm
- Credit card footprint about 0.16 in thick, so it slips into a wallet or pocket instead of a drawer or a phone
- Twenty button keypad with letters, numbers and symbols plus New, Edit, Erase and Enter keys, and a four line LCD for reading codes back
- One master code unlocks every stored code, and four incorrect entries erase all of them automatically, which protects the data if the device is lost
- Completely offline with no USB, Bluetooth or internet connection, which keeps the codes out of reach of phishing, keyloggers and cloud breaches
