How to Toggle ‘Open at Computer Login’ in Signal Desktop
Signal Desktop opening at computer login controls whether the messaging app starts automatically when you turn on your Windows PC. This setting launches Signal right alongside Windows so you see new messages the second your desktop appears.
Turning on this feature means you never miss a chat, while turning it off speeds up your startup time and saves computer memory.
Open Signal Desktop, go to Preferences General, and check or uncheck the ‘Open at computer login’ box. This setting controls whether Signal automatically launches when you start your computer.
Steps to Toggle Open at Computer Login
Getting Signal to launch on startup takes a few clicks inside the app preferences, controlling whether the software boots alongside the operating system or waits for a manual launch.

2. Alternatively, launch Signal from the Taskbar or Taskbar overflow.

3. Once the app opens, click File and select Preferences. Keyboard shortcuts include pressing CTRL + , or selecting the Settings (gear) icon in the bottom left corner.

4. Navigate to the Preferences window, select General on the left side, and locate the System section on the right.
5. Check the 'Open at computer login' box to enable automatic launching, or uncheck it to prevent the app from starting with the system.

6. Background execution without a visible window requires checking the Minimize to system tray box.

Enabling Minimize to system tray forces the application to run quietly inside your Taskbar app overflow pane.
Troubleshooting Signal Startup Issues
Startup failures require inspecting operating system configurations to resolve Signal not opening at startup.
Summary
Configuring startup preferences dictates whether background launching occurs during login, contributing to optimal computer performance.
Why does Signal keep asking for a password on startup?
Signal prompts for a password when app lock is active as a security measure protecting chat histories. Disabling app lock within Privacy settings bypasses this requirement, though doing so reduces local message database security.
Does disabling 'Open at Login' stop Signal from receiving messages?
Active background execution remains necessary for server connectivity and incoming message retrieval. Notifications and updates arrive exclusively after launching the application manually to establish server communication.
How do I fix Signal not opening at login on 🪟 Windows 11?
Resolving login startup failures on Windows 11 involves verifying application preferences before inspecting the operating system startup directory.
