As threats like fraud, abuse, and AI grow more sophisticated, Indeed has evolved its approach to user verification, transforming the phone number from a basic security tool into a dynamic trust signal. What began as two-factor authentication with Twilio Verify now leverages Twilio Lookup to assess phone number’s signals, playing a central role in detecting linked accounts, supporting account recovery, and identifying high-risk activity across the platform. This session explores how Indeed uses real-time mobile signals to proactively mitigate abuse, protect users, and build trust at scale in a rapidly changing landscape.
