Secure & Random
Passwords are generated using an industry-accepted cryptographically strong pseudo-random number generator (PRNG) seeded with virtually unknowable system-level entropy source unique to your own device.
Is Your Password Strong Enough?
The strength of a password (its entropy) is based on the varying degrees of freedom provided to the random password generating method. Entropy measure how difficult it would be to crack a given password through guessing, brute force cracking, dictionary attacks or other common methods.
The main components of determining the entropy of a password or passphrase are:
- The size of the character or word pool used – this includes all variations of upper and lower cases, symbols, numbers, etc, while it excludes all specified disallowed symbols
- The forced minimums imposed on the passwords (for example if at least one symbol is required, etc.)
- The length of the password or number of words in the passphrase
- The delimiter (and the delimiter length) used in the passphrase
Based on contemporary computational power, the resulting password strength is determined according to the following chart:
| Bits of Entropy | Strength | Suitability |
|---|---|---|
| < 28 bits | Very Weak | Might keep out family members |
| 28 – 35 bits | Weak | Should keep out most people, often good for desktop login passwords |
| 35 – 59 bits | Reasonable | Fairly secure passwords for network and company passwords |
| 60 – 127 bits | Strong | Suitable for guarding financial information |
| 128+ bits | Very Strong (Ludicrous) | Often overkill |
Security Features
No Networks – generated passwords/passphrases are known only to you
Passwords are 100% generated client-side on your computer, and are NOT transmitted – and cannot be sniffed – over any network.
We do not store any passwords.
Completely unpredictable
Passwords are generated completely randomly within the degrees of freedom which are allowed by the user. Aside from the provided settings, the password generation output is completely out of your hands and cannot be reproduced – even by someone who knows you well.
Assumes the worst
Entropy computations are performed with the assumption that any potential attacker is already aware of the process and settings used in generating these random passwords. With this in mind, passwords are generated completely randomly using the remaining degrees of freedom available.
