# `Macaw.Auth.Native.Hasher.Argon2`
[🔗](https://github.com/dcoai/macaw_auth/blob/v0.4.1/lib/macaw/auth/native/hasher/argon2.ex#L2)

Argon2 (`:argon2_elixir`), compiled only when that library is loaded.
The parameters are argon2_elixir's own settings (`config :argon2_elixir,
t_cost: 3, m_cost: 16, parallelism: 4, argon2_type: 2`); a hash made
with others is rehashed at sign-in.
