Fast Login
by peinzlou
Fast Login is a Fabric client mod that stores a server password in an encrypted vault and enters it for players joining a server, so the password is typed only once.
What it does
Players bind a key to a stored password, and the password is typed into the login prompt without being shown on screen, so others watching a shared screen cannot read it. A menu opened with F7 lists the saved entries, and each one can be filled in automatically. Passwords are kept in an encrypted form inside the game folder, in a file named vault.json under the fastlogin directory.
The mod detects login text in the chat that signals a proxy waiting for a password, and then enters the stored password on the player's behalf. Captcha prompts still need a person to solve them; the mod handles the rest of the sequence. Players can also register server commands of their own, so the login steps can be tied to the commands they already use.
Fast Login is a client-side only mod for Fabric, built for 1.21.11 and released under the MIT License, though it is not open source. Only the player's client needs it. Latest file is 1.1.0, published on 2026-07-15, after the first release on 2026-04-13.
Key features
Key-bound password input
A chosen key types the saved password into the login field, so no one watching the screen sees the characters.
Encrypted password vault
Saved passwords are stored in encrypted form in a local vault file rather than in plain text.
Automatic proxy login
When chat shows a proxy login prompt, the stored password is entered without pressing a button.
Menu with F7
Pressing F7 opens a menu of saved passwords and buttons that fill them in, with an automatic option in the mod menu.

Sometimes you are in a call with friends, sharing your screen, or streaming live. You join your favorite server and need to enter a password, but to keep it private, you have to stop sharing your screen first.
