Password resistance calculator
Compare the random scale on numbers. This is an educational model; you do not enter a password here.
Calculation assumptions
The model assumes independent, evenly random characters. It does not evaluate the password arranged by man.

Result for current assumptions
94 characters to choose from · length: 16 · number of attempts per second: 10.
- Combinations
- ≈ 3,71 × 10^31
- Model entropy
- 104.9 bit
- Average time in the model
- 5,88 × 10^22 years
The time is rounded down to the given unit. The very large values are shown approximately: × 10^n is multiplied by ten to the n power.
Compare lengths with the same assumptions
Only the length changes. The number of characters available and the pace of attempts remain the same as in the form. This is an example of model action, not rating a real account.

Assumptions
We calculate the average number of attempts on an evenly random selection. The scripts are only illustrative; the source of password quality is randomness, length and account protection.
