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.

- Create an encoded Argon2 hash
Frequently Asked Questions
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.
