What it is
Argon2id is a password-based key-derivation function. It turns a password into cryptographic protection while making large-scale guessing deliberately expensive.
How it works
It takes your password, a unique salt, and carefully chosen memory and time settings to derive key material. Each guess needs real work and memory, which makes a large guessing attack slower and more expensive.
What it means for Stax Pass
Stax Pass uses Argon2id to derive protection from your password. Its memory-hard design helps resist attackers who try huge numbers of guesses with specialized hardware.
In Stax Pass, this part of the design helps protect the path into your password manager. Your password and recovery material are important because they help control access to the keys used for protected records; the service is not meant to hold a simple readable substitute that can unlock everything for you. It does not make a weak or reused main password safe, which is why your Stax Pass password should be long, unique, and kept separate from other accounts.
What it means for you
A memorable password still needs careful protection. Use a long unique password for Stax Pass and keep your recovery phrase somewhere safe. You do not need to operate the cryptography yourself; your role is to protect your Stax Pass password and recovery phrase, and stay alert to scams.
