なぜ Google Password Manager から離れる？
Password managers are security-critical. Dedicated tools offer better audits, features, and independence—and avoid losing passwords if Google suspends your account.
Googleの限界・リスク
- • Fully tied to Google account—suspension risks password access
- • Not zero-knowledge—Google can technically access stored passwords
- • Limited passkey, 2FA, and secure sharing features
- • Constrained use outside Chrome and certain OS integrations
