Visitor mode allows you to manage devices on the Mobile Client without registration. When you log in as a visitor, a visitor account will be created for you automatically, and the account will not change on the same phone.
For information security, please use visitor mode cautiously, which is NOT password-protected.
In visitor mode, you can only manage your devices on a same phone. To avoid this inconvenience, you can register an account. For details about registering account in visitor mode, see Register an Account in Visitor Mode.
