About this Tool
Use this Argon2 generator to test Argon2id parameters and create development password hashes locally in your browser. Configure the memory cost, iteration count and parallelism while keeping values within safe browser limits.
Examples
- Generate an Argon2id hash
- Test a 64 MiB memory cost
- Create an encoded Argon2 hash
Frequently Asked Questions
Which Argon2 variant should I use?
Argon2id is generally the preferred variant for password hashing because it combines resistance to side-channel and GPU-based attacks.
What does the memory cost control?
The memory cost determines how much memory the hashing operation requires, making large-scale attacks more expensive.
Can Argon2 run in the browser?
Yes. Argon2 can run locally through a browser-compatible WebAssembly implementation.
