Strong Password Generator: How Strong Is Your Password?
The most objective way to measure password security is to calculate the number of possible combinations. The larger this number, the longer a brute-force attack would take. This tool uses your password policy parameters to calculate how many unique passwords can be formed at each length.
Alphabet Size and Combination Count
Total combinations = (alphabet size)^(password length). Alphabet size includes: lowercase (26) + uppercase (26, if case sensitive) + digits (10, if enabled) + special characters (0–32, per setting).
| Alphabet | Length 8 | Length 12 | Length 16 |
|---|---|---|---|
| Lowercase only (26) | ~2.1×10¹¹ | ~9.5×10¹⁶ | ~4.4×10²² |
| + Uppercase (52) | ~5.3×10¹³ | ~3.9×10²³ | ~2.8×10³³ |
| + Digits (62) | ~2.2×10¹⁴ | ~3.2×10²¹ | ~4.7×10²⁸ |
| + Special (94) | ~6.1×10¹⁵ | ~4.8×10²³ | ~3.7×10³¹ |
Strong Password Tips
- Use at least 12 characters — length increases combinations exponentially.
- Mix uppercase, lowercase, digits and special characters.
- Avoid dictionary words and personal information.
- Use a different password for each account — a breach shouldn't cascade.
- Use a password manager to store complex passwords securely.
