Stop using the same password across different services, use a password manager instead. Here is one of the most suckless password manager, pass (This exist on most distro’s software repo!).
Initial setup
Create a gpg key and setup a passphrase, which serve as the master password.
gpg --full-generate-key
Then initialise the pass directory.
pass init "key"
Add passwords
Use the following command to add passwords, it can be in a subdirectory,
pass insert email/example@gmail.com
then type in the password twice. Or use pass to generate password of 20 characters using the following command.
pass insert email/example@proton.me 20
To create multi-line passwords.
pass insert -m account/vpn
Then insert multi-line password, and hit ctrl+d to exit.
List passwords
To view a list of created passwords, just use the command pass, it will give the following output.
Password Store
├── account
│ └── vpn
└── email
├── example@gmail.com
└── example@proton.me
View passwords
To show the password in the terminal, use the following command and type in the master password.
pass show email/example@gmail.com
Or directly copy to clipboard without displaying in terminal.
pass show -c email/example@gmail.com
Change master password
gpg --edit-key $(cat .password-store/.gpg-id)
Enter the command passwd, enter current password in the prompt, then enter new password. Lastly, save it using the save command.
