Passkeys vs. passwords: What comes after the password?
Passkeys move authentication away from the classic password. However, they do not solve all security questions and do not eliminate passwords overnight.
What passkeys do differently
Passkeys replace the classic secret that users have to know and type in with a more modern model with device-bound cryptographic keys.
This reduces the dependency on password quality, reuse and many phishing scenarios.
Why passkeys are attractive
- No manual password management per service necessary.
- Less risk from reuse and bad passwords.
- Often better user experience via device login, biometrics or hardware authenticators.
Why passwords still remain relevant
Not every service fully supports passkeys, and hybrid transition models exist in many environments. That's why good password practices will remain relevant for a long time.
For users, the goal is not ideological change, but rather less real attack surface in everyday life.
Quick checklist
The most important actions from this guide in compact form.
- Activate passkeys where the service supports them properly.
- Nevertheless, continue to strongly secure existing password accounts.
- Understand recovery and device replacement processes in advance.
