How this service works
Check password strength with entropy and crack time
Output
Returns a password strength assessment including entropy bits, estimated crack time (e.g. '3 years', 'instantly'), and a strength rating or score indicating how secure the password is.
Example use cases
Example prompt
“Can you check how strong the password 'Tr0ub4dor&3' is and tell me its entropy and how long it would take to crack?”
Technical details
Endpoint
GEThttps://password-strength.api.klymax402.com/api/checkWhen to prefer
Use this endpoint when you need to programmatically assess password strength with quantitative metrics like entropy and crack time estimates, rather than just a simple weak/strong label. Ideal for security audit flows, registration validation, or user-facing password feedback.
Side effects
- Missing password parameter returns an error
- Empty string password may return a minimal or zero-strength result
- Extremely long passwords may hit length limits
- Network timeout on the remote API returns no result
