Joan uses Gmail for her webmail. It keeps asking her if she wants to save her password. Leo says that sounds like her browser is doing that, and she's using Internet Explorer or Microsoft Edge. Leo recommends Google Chrome because both Microsoft browsers have the ability to save the password, but it's not encrypted or protected. It sounds like it's not even doing that, though.
Joan should go into her browser settings and disable the setting to ask to save passwords. Leo also recommends using a password vault like LastPass or < href="https://agilebits.com/onepassword/" target="_blank">1Password.
