- Entropy
- 102.8 bits
- Strength
- Very strong
- Character pool
- 86 chars
How it's calculated
Entropy (bits) = length × log₂(pool size). ~60+ bits recommended for online accounts.
Common questions
Is this password truly random?
It's deterministic from the seed so you can reproduce it. For maximum secrecy, use your OS keychain — but the entropy shown reflects the search space an attacker sees.
How do I regenerate?
Change the 'Regenerate' number — any tweak gives a completely different password.
