Passkeys vs OTP: what changes for your sign-in

Passkeys are replacing OTP for sign-in by using a private key stored on devices and a public key on servers, requiring biometric authentication to prevent phishing. Simultaneously, digital visibility is evolving through SEO, AEO, and GEO. These are not competing replacements but overlapping outcomes focusing on search rankings, direct answers, and AI-generated responses. Companies should implement one coordinated strategy rather than disconnected teams to manage visibility across Google AI Overviews and platforms like ChatGPT.
