Rolling out passkeys to a consumer base

Starting state

• Password plus optional MFA, with meaningful account-takeover risk
• Login friction and reset volume dragging on conversion

Trigger for change

• Rising ATO and credential-stuffing pressure
• A push to reduce password-reset support load and login friction

Constraints

• No user left unable to log in; fallbacks must remain
• Cross-platform passkey support is uneven; handle gracefully

Architecture choice

• Offer passkeys alongside existing methods first
• Nudge enrollment at low-friction moments (post-login, checkout)
• Keep social and email OTP as fallbacks; make passkeys the default later

Rollout plan

1. 1

   Offer

   Enable passkeys as an optional method; measure enrollment.

2. 2

   Nudge

   Prompt enrollment at natural, low-friction moments.

3. 3

   Prefer

   Surface passkey as the primary option for enrolled users.

4. 4

   Default

   Make passkeys the default for new accounts; retain fallbacks.

Typical outcomes

• Phishing-resistant login for the enrolled majority
• Lower reset volume and smoother login for passkey users
• No user stranded, fallbacks remain for edge cases

Lessons learned

• Roll out by nudging, not forcing; measure enrollment before defaulting
• Fallbacks are mandatory given uneven cross-platform support
• Enrollment timing matters more than the enrollment UI itself

FAQ

Should I force passkeys on all users?

No. Roll out by offering passkeys, nudging enrollment at low-friction moments, then defaulting for new accounts, always keeping fallbacks. Forcing them strands users on platforms with uneven support.

When should passkeys become the default?

Once you've measured healthy enrollment and success rates among users who opted in. Make passkeys the default for new accounts first, and retain social and OTP fallbacks for the rest.
