Change your passphrases often for all online accounts. Generate a secure, unique passphrase for each separate account. Research different passphrase manager services* to find one that works best for you: NordPass, Keeper, RoboForm, Dashlane, and 1Password. If you’re uncomfortable storing your passphrases with a third-party cloud provider, there are passphrase managers such as the award-winning KeePass Password Safe that allow you to store them in your own secure location, through an encrypted database locked with a master key.
