Simple Login
by SpicyMikeHUN
Simple Login gives a Fabric server a password-based login and registration system, with optional two-factor authentication for accounts that need it.
What it does
Players register an account and then log in with a password before they can play. Passwords are hashed with BCrypt, and account data is kept in an SQLite database. Players who are not logged in stay under pre-login protection, which restricts what they can do until they authenticate.
Two-factor authentication uses TOTP codes compatible with Google Authenticator and can be switched on globally by the server owner. A session system with trusted IP support reduces how often a player is asked for a code. A deletion request for an account is only carried out after the player types /delacc confirm, and any pending request stops being valid once its time window runs out. An automatic update checker notifies server owners about new releases.
Simple Login is a Fabric mod and is also available for Paper, Spigot, Bukkit, Purpur and Folia. It is published for 1.17 – 26.2 with 33 release versions, and 1.16.7 for 1.19.2 is the latest Fabric file, dated 2026-09-27. The mod is released under All rights reserved and is not open source. Its public issue tracker is the only public link listed.
