How to Change Your Login Password on Debian When You Forgot It

Forgetting your login password on Debian can be frustrating, but there are steps you can take to reset it and regain access to your system. Here's a detailed guide on how to change your login password on Debian:

1. Access Recovery Mode: If you forgot your password, you can reset it by booting into recovery mode. Restart your system and hold down the Shift key to access the GRUB menu. Select the Advanced options for Debian and then choose the recovery mode option.
2. Drop to Root Shell: In recovery mode, select the Root Drop to root shell prompt option. This will give you a root shell with the necessary permissions to change the password.
3. Change Password: Once in the root shell, you can use the passwd command to change the password for a specific user. Simply type passwd username and follow the prompts to set a new password.
4. Reboot System: After changing the password, reboot your system by typing reboot in the root shell. You can now log in with your new password.

It's important to keep track of your passwords and consider using a password manager to securely store and manage them. This will help prevent future lockouts and make it easier to reset passwords when necessary.
