Secure Password Generator
Generated Password
Select at least one character set
Strength: Very Strong155-bit entropy
Password Best Practices
- Use at least 16 characters for critical accounts.
- Never reuse passwords across websites.
- Store passwords in a trusted manager.
Security Note
- Entropy is a strong indicator, but your overall security also depends on account protections and breach hygiene.
Why Use This Generator
This password generator uses cryptographically secure randomness from your browser to produce hard-to-guess passwords. You control the character pool, length, and readability options, while the entropy meter gives a fast security estimate before you copy.
How to Use
- 01Set length and character groupsMove the slider and enable uppercase, lowercase, numbers, and symbols according to your policy.
- 02Enable ambiguity filtering if neededUse the ambiguity toggle to remove O, 0, l, and I when humans need to read or type the password.
- 03Review strength and copyCheck the entropy and strength indicator, regenerate if required, then copy the final password.
Reference Table
| Security Level | Entropy Range | Typical Use Case |
|---|---|---|
| Weak | < 64 bits | Temporary or low-value local use only |
| Fair | 64-79 bits | Basic online accounts |
| Good | 80-99 bits | Primary email or social accounts |
| Strong | 100-127 bits | Banking, work, and sensitive systems |
| Very Strong | 128+ bits | Critical admin credentials and vault master passwords |
FAQ
Each additional character multiplies the total search space. A longer password with a good character pool usually improves brute-force resistance more than replacing one character with a symbol.
