Welcome to Android Central! DO NOT GIVE THAT INFORMATION. It sounds like a phishing scam. You probably installed some kind of adware/malware inadvertently while installing some other app. Start by uninstalling apps one by one to see if that goes away.

Alternatively, do a factory reset:

1. Make sure your important data is backed up or saved to the cloud.
2. Go to Settings>Backup & Reset, and uncheck Automatically Restore.
3. Do the Factory Reset.
4. Right after the Setup Wizard is done, go immediately to the Play Store and stop any automatic installations that might be occurring.

Now see if the popups persist. If not, start reinstalling your apps one by one. Be cautious with games, "RAM booster/cleaner" apps, "free" music/video downloaders, and porn.
