You shipped a new login method. What does it actually bring? Method Uplift compares every method bundle on the same traffic, so you answer with numbers instead of opinions.
Read-only, works on top of your existing IdP
Password, passkey, social and OTP in one view
Uplift measured against the password baseline
The victory-lap trap
“Passkey users succeed 98%” sounds like proof. It is not. Method Uplift compares bundles on one denominator and Experiments proves the fix.
Per-method averages flatter you: passkey users are your most engaged users. Bundles are compared on the same traffic instead.
Login runs between app, browser and device, where IdP, APM and SIEM logs stop. Method Uplift measures what your backend never sees.
Each bundle row ends in one number: the uplift over password alone. That number decides if a method earns its place.
Three views answer the mix question: which bundles exist in your traffic, how they perform against the password baseline and where the winner changes.
Password alone, password + passkey, password + social, all three. Each bundle is measured on the same engaged-flow denominator, with the uplift over the password baseline in percentage points.
