So you've just lost your device (sorry about that) and you realize you've been using Firefox Sync to get all of your usernames and passwords on it. This article describes what you should do to prevent someone from accessing your passwords.
First, change your sync password from a synced computer
This first step will prevent your lost phone from connecting to the sync server and getting all of the new passwords that you will have to create.
- (In Firefox for desktop) Click the menu button
to open the menu panel.
- Click your Mozilla account name or email address (or click ).
- Click
- Alternatively, go to Mozilla account Sign in.
- On the Mozilla account page, scroll down to the Security section and click the button next to Password.
- Follow the steps to enter your old and new passwords, then click to finish.
Second, change all of your account passwords from a synced computer
This part is more time consuming but important. If you don't change the passwords for things like your bank account, it would still be possible for someone else to log in to your account on your lost device.
See Choose a strong password for an easy way to create better passwords.
