Frequently Asked Questions
What is Argon2?
Argon2 is a password hashing algorithm that won the Password Hashing Competition in 2015. It is designed to be resistant to GPU and ASIC attacks through configurable memory usage.
What is the difference between Argon2i and Argon2id?
Argon2i is optimized for resistance to side-channel attacks. Argon2id is a hybrid that provides both side-channel resistance and GPU attack resistance. Argon2id is recommended for most use cases.
What parameters should I use?
OWASP recommends Argon2id with 64 MB memory, 3 iterations, and 1 thread as a minimum. Increase memory and iterations for higher security.
Is Argon2 better than bcrypt?
Argon2 is considered more modern and flexible. It allows tuning memory usage independently from CPU cost, making it more resistant to specialized hardware attacks. However, bcrypt remains secure and widely supported.
Is my password stored?
Your password is sent to the server only for hashing and is immediately discarded. We do not log or store any data.
