من واقع تجربة شخصية : استخدام حساب البريد من الـ Gmail أكثر أماناً

Quote: Each time you sign in from an unverified computer, you will be required to verify your identity with both a password and a verification code, which you can get via a mobile app, SMS text message, or phone call. IMPORTANT: What to Do If Some Applications Stop Working Some applications that access Google data do not accept verification codes. They only accept usernames and passwords. Examples include: -Smartphones (e.g., Android, iPhone) -Mail clients that use IMAP/POP (e.g., Outlook Express or Thunderbird) -Chat clients (e.g., Google Talk) -Picasa desktop application Now that you have signed up for 2-step verification, these applications will temporarily stop working. You can get them working again by entering an application-specific password into the password box, instead of your regular password or your verification code. IMPORTANT: Don't Lose Access to Your Account Your account now requires both a password and a verification code for access. If you lose access to the phones you configured for retrieving codes you can lose access to your account. Please keep your backup codes (the codes you printed out when signing up for 2-step verification) in a safe place. You can use these in place of your verification code. If your phone or mobile application is unavailable, these codes will be the only way to sign in to your account..
