summary
Claims that 81% of password breaches come from weak passwords and 34% of users reset passwords monthly, and reports of 95% fewer resets and a 4x increase in login success after switching to passkeys. Shows concrete Android steps: create a digital asset link, call the credential manager API, send server challenge, let the credential provider generate a private key stored on-device and return the public key, and verify signed challenges while using the built‑in bottom sheet and biometric or screen‑lock authenticators.
