Master password protects your passwords
To ensure that your passwords are safe even if someone gets hold of your device, be sure to set a master password for Firefox’s password management. You can set one under Settings > Security. Here, choose a password that is secure but easy to remember. From now on, this is the only password you need to know by heart.
Unfortunately, Firefox’s password management lacks an integrated password generator. However, with the add-on pwgen – password generator this functionality can be easily added. After installing pwegen, a red “P” on a black background appears in the upper right corner of Firefox. One click is enough to generate a random password and copy it to the clipboard. With Ctrl + V you can paste the new password into the corresponding field. To increase the security of passwords generated this way, we recommend setting the password length to at least 14 characters. You adjust this in the default settings of pwgen. You can access the settings via the arrow next to the “P”. Set all checkmarks under “general settings” and set the desired password length under “extras”.
