Frequently Asked Questions
What cost factor should I use?▾
10 is the standard default. Use 12 for high-security applications. Higher values are exponentially slower: cost 12 takes ~4x longer than 10.
Is it safe to use in the browser?▾
For testing and development, yes. For production password hashing, always do it server-side. This tool is great for verifying hashes or generating test data.
