The Secret Manager
Ubuntu utilizes a background service called the GNOME Keyring (often managed via the “Seahorse” GUI application) to securely store your passwords. When you log into an application (like Skype or a saved Wi-Fi network), the system asks if you want to remember the password. If you say yes, Ubuntu automatically saves this credential into the “Login” keyring. Normally, this keyring unlocks automatically when you type your main user password to boot up the computer. However, if you use an auto-login feature to bypass the boot screen, the keyring remains locked, and Ubuntu will constantly bombard you with annoying pop-ups asking for a password to unlock the saved passwords every time you open a basic app.
Disabling the Keyring Lock
To stop the constant pop-ups and prevent Ubuntu from automatically securing your saved passwords behind a secondary lock (especially if you use auto-login), you must set the keyring password to blank.
Warning: This means your saved passwords are stored locally unencrypted. Only do this on a secure desktop locked in your home, never on a laptop. Open the applications menu and search for Passwords and Keys (or type seahorse in the terminal). In the left sidebar, under “Passwords,” locate the folder named Login. Right-click on it and select Change Password. You will be prompted to enter your old password (your current user password). When it prompts you to enter the new password, leave both fields completely blank and click Continue. Ubuntu will warn you that this stores passwords unencrypted. Accept the warning. The keyring will now open silently without ever prompting you.
