Use Case
Add Communication to Your Login Security Layer
Alerts can inform a user about a login or security-sensitive change, but messaging should complement—not replace—strong authentication, session security and risk controls.
Security Alert Examples
- Login OTP.
- New device sign-in.
- Password changed.
- Mobile/email changed.
- Security setting changed.
- Suspicious activity notice.

Never send passwords, permanent credentials, full API keys or unnecessary personal information in notification content.
