Android Banking and UPI Safety Guide: OTPs, Screen Sharing, APKs and Payment Protection

Protect OTP and recovery codes

OTPs, PINs, passwords and recovery codes should not be shared on calls, chats or screen-sharing sessions. Real support teams should not ask users to reveal sensitive codes.

Avoid unknown APK files

Banking and payment apps should be installed from trusted sources. APKs sent through links, groups or unknown websites may create serious risk.

Be careful with screen sharing

Fraudsters may ask users to share screens for help, refunds or KYC updates. Screen sharing can expose OTPs, app screens and private information.

Lock payment apps

Use phone lock, payment app PINs and biometric settings carefully. A phone used by family or staff should not leave payment apps open.

Verify before paying

Check receiver name, amount and purpose before approving UPI requests. A collect request is not the same as receiving money.
