{"slug":"best-device-intelligence-apis-for-account-takeover-prevention","title":"Best device intelligence APIs for account takeover prevention","question":"What are the best device intelligence APIs for account takeover prevention in 2026?","verdict":"As of 2026-08-09, Claude and Gemini collectively rank Fingerprint #1 for device intelligence apis for account takeover prevention on ModelsAgree by aggregate score. The models' case: Delivers industry-leading persistent device identification accuracy across web and mobile browsers even through incognito mode or IP resets, offering lightweight. The models' main caveat: Provides only raw device identifiers and signal intelligence rather than built-in fraud orchestration, rule engines, or automated user challenges out. The strongest alternative is SEON — Device fingerprinting combined with digital footprint/email-phone enrichment gives strong signal for ATO detection without invasive SDK friction. Not unanimous: Claude picks SEON.
