Are Remember Me functions in Web browsers or other applications unsafe and should be avoided?

True

If you save your password on a public computer the next person to use that computer may access your accounts. This might also apply to your home computer or laptop; if curious siblings or parents have access to your machine they may be tempted to log into your accounts. Never save username and password details on your smart phone, within messages or your web browser, if it gets lost or stolen someone could compromise all of your online accounts.
