How this service works
Score a password by length, character classes, and estimated entropy (bits).
Output
Returns a strength score, estimated entropy in bits, breakdown of character classes present (uppercase, lowercase, digits, symbols), length evaluation, and an overall password quality rating.
Example use cases
User registration password validation
“Before I let a user finalize their account, check if the password 'Summer2024!' is strong enough — I need the entropy score and character class breakdown.”
Password policy enforcement audit
“I need to audit a batch of candidate passwords — start with 'correct-horse-battery-staple' and tell me its entropy bits, length score, and overall strength rating.”
Security education feedback tool
“A user just typed 'password123' into my form — can you score its strength and explain what character classes it's missing so I can show them helpful feedback?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/password-strengthWhen to prefer
Use this endpoint when you need a quick, deterministic, server-side password strength evaluation based on entropy estimation and character class analysis — ideal for form validation, registration flows, or security audits. Prefer it over client-side libraries when you want a consistent, backend-enforced scoring standard or when operating in an agent workflow that requires a structured API response.
Side effects
- Empty or missing password field returns validation error
- Extremely long passwords may be truncated or rejected
- Non-UTF-8 or binary input may cause parsing errors
- Network timeout for slow connections
