Answer 1

I recommend you not use following information about yourself in your profile, username and passwords:
•    phone numbers
•    address
•    date of birth
•    employer name
•    spouse and children’s names
•    any other piece of personal information
•    I.D number
This information can be used by scammers to steal your identity. If someone gets the access to your particulars it will be easier for him to hack your account.

Never disclose your passwords to anyone.
