As always a basic and simple guide to change user password in Linux Mint.
1- Open menu and search "settings".
Alternatively, if you already know how to do it, open the System Setting - Control Center.
2- Open Account details
3- Click in the Password selection, click exactly above the black dots to open the window for entering the new password.
Always remember the new password you wrote and do not write it in any memo, notes, digital or paper.
- Sometimes remember to change your password.
- Never use too simple combinations, eg: 123456789
- Use small and large fonts with numbers, if you want also use some special characters, eg: PizZaWithMozzarella2023??!
