For Gmail, open your Google Account, choose Security, then 2-Step Verification. Enroll an authenticator app by scanning the QR code, confirm codes, add backup options, and print backup codes. For Outlook or Microsoft, visit Security dashboard, turn on Two-step verification, add an app or key, confirm sign-in methods, and store recovery codes. Verify on all devices. Email controls many resets, so treat this setup as the crown jewel of your defenses.
Find Security or Password and security settings, enable two-factor authentication, and choose an authenticator app over SMS when possible. Confirm code entry, then save recovery codes. Review logged-in devices and remove unknown sessions. Turn on login alerts. Avoid approving prompts blindly on mobile. If traveling, test access before leaving. These accounts carry identity and reputation weight; containment is easier when extra verification stands between an attacker and instant messaging reach.
Financial institutions vary widely. Some offer authenticator apps, push prompts, or hardware tokens; others restrict to SMS. Enable the strongest available method immediately, then ask support about more secure options. Verify international phone compatibility before travel. Set transaction alerts and daily limits. Store support numbers offline. Keep backup codes in a safe place, separate from cards. When accounts hold money, the slight inconvenience of extra steps pays dividends in prevented fraud and quick recovery.
