About credential.help
Simple, privacy-friendly tools for passwords, tokens, and identity.
Designed for people who care about security but don't want to give their credentials to yet another random website.
Built around strong passwords
Start with the strong password generator and password strength checker. Generate long, unique passwords and immediately check for weak patterns, reuse risks, and entropy—without storing or uploading your secrets.
Developer-focused utilities
For developers, there are tools for API keys, UUIDs & ULIDs, JWT decoding & generation, SHA-256 / SHA-512 hashing, and random strings. Perfect for local development, testing, and debugging auth flows.
No logins, no tracking, no sync
credential.help doesn't require an account or sync data. Tools rely on browser APIs like crypto.getRandomValues and crypto.subtle so that passwords, tokens, and hashes are generated and processed locally on your device.
When should I use these tools?
Use credential.help when you're setting up new accounts, cleaning up old weak passwords, or working on authentication and API integrations. It's ideal for quickly generating secure credentials, testing JWTs and hashes, or creating IDs and usernames for prototypes and side projects.
Do I still need a password manager?
Yes. These tools help you create and inspect credentials. A password manager securely stores them and autofills them across devices. The best setup is: use credential.help to generate strong passwords and passphrases, then save them in your manager as the single source of truth.
