of protection features and some of the required credentials:

Protection by my
Xperia
If you remotely reset your device using this service, you must enter the username and
password for a Google™ account associated with the service. The device must be
connected to the Internet before the setup process can be completed. Otherwise, you will
not be able to use your device after the reset.

password for a Google™ account. The device must be connected to the Internet before
the setup process can be completed. Otherwise, you will not be able to use your device

Software repair
If you use the Xperia™ Companion software to perform a software repair, you’re asked to
enter your Google™ account username and password when you start the device after the
repair is complete.
For Android™ Device Manager, it is necessary to enter information from a Google™ account.
This can be any Google™ account which you have set up on the device. If you cannot provide
the relevant account information during a setup process, you won't be able to use the device
at all.
