How this service works
Score a password by length, character classes, and estimated entropy (bits).
Output
Returns a strength score or rating for the submitted password, along with a breakdown of its length, character classes used (uppercase, lowercase, digits, symbols), and estimated entropy in bits.
Example use cases
User registration password validation
“Before I let users submit their registration form, check if the password 'Summer2024!' is strong enough — give me its entropy bits and strength rating.”
Security audit of existing passwords
“I'm auditing my accounts — can you score the strength of the password 'correcthorsebatterystaple' and tell me how many bits of entropy it has?”
Password policy enforcement check
“My app requires passwords with high entropy — score 'xK9#mP2$qL' for me so I can see its length, character classes, and entropy estimate before enforcing the policy.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/password-strengthWhen to prefer
Use this endpoint when you need a fast, deterministic computational strength score for a password based on entropy, length, and character diversity — not a breach database lookup or policy compliance check. Ideal for real-time form validation, security audits, or password policy enforcement flows where raw entropy metrics matter.
Side effects
- Missing or empty password body returns a 400 error
- Extremely short passwords may return minimal entropy values
- Non-UTF8 or binary input may cause parsing errors
- API key or payment authentication failure returns 401/402
