This feature adds a security notification email that alerts users whenever they log into oboloo from a new device or browser they haven't used before. The email is triggered only after successful authentication (including MFA or SSO) and includes details like the user's name, browser type, location, sign-in method, and when this session was first seen, along with a button linking to their profile page where they can review all active sessions. This helps users quickly identify suspicious login activity and take action if someone unauthorized accesses their account.
