pattern? to sign in to the Google account you have added on the phone

Protecting your phone with encryption
You can encrypt all the data on your phone: Google Accounts, application
data, music and other media, downloaded information, and so on. If you
do, you must enter a numeric PIN or a password each time you power on
your phone.
Warning! Encryption is irreversible. The only way to revert to an unencrypted
phone is to perform a factory data reset which erases all your data.
Encryption provides additional protection in case your phone is stolen and
may be required or recommended in some organizations. Consult your
system administrator before turning encryption on. In many cases the PIN or
password you set for encryption is controlled by the system administrator.
Before turning on encryption, prepare as follows:
• Set a lock screen PIN or password.
• Charge the battery.
• Keep the phone connected to the charger.
• Schedule an hour or more for the encryption process. You must not interrupt
it or you will lose some or all of your data.
When you’re ready to turn on encryption:
1. From the home screen, tap the Menu key > System settings > Security >
Encrypt phone.
2. Read the information about encryption carefully.
The Encrypt phone button is dimmed if your battery is not charged or your
phone is not plugged in.
If you change your mind about encrypting your phone, tap the Back key.
Warning! If you interrupt the encryption process, you will lose data.
3. Tap Encrypt phone.
4. Enter your lock screen PIN or password and tap Next.
5. Tap Encrypt phone again.
The encryption process starts and displays its progress. Encryption can take
an hour or more, during which time your phone may restart several times.
When encryption is completed, you’re prompted to enter your PIN or
password.
Subsequently you must enter your PIN or password each time you power on
your phone in order to decrypt it.
