14 character password generator
Made on your device. Never sent or stored.
A random 14 character password, generated on your device. Change the character types below; the length stays at 14 unless you move it.
Is 14 characters long enough?
Fourteen characters with all types gives about 90 bits. It is one character short of the NIST minimum for a password used as the only factor.
When to use it: Good for accounts where a field caps length at 14, which still happens on some older systems.
How strong is a 14 character password?
A random 14 character password from letters and digits has 83.4 bits of entropy. With symbols added it has 90.2. Here is how that translates into guessing time for each character set.
| Characters | Pool | Bits | Fast hash | Slow hash |
|---|---|---|---|---|
| Digits only | 10 | 46.5 | 1 hour | 158 years |
| Lowercase letters | 26 | 65.8 | 102 years | 102 million years |
| Letters, both cases | 52 | 79.8 | 2 million years | 2 trillion years |
| Letters and digits | 62 | 83.4 | 20 million years | 20 trillion years |
| All four types (this site) | 87 | 90.2 | 2 billion years | 2 quadrillion years |
These figures only hold for random passwords like the ones above. A 14 character password you made up, with words, names or dates, is guessed far sooner. Test one with the strength checker.
