Passkey, password and social, side by side on the same production traffic: how often each method is present, how often flows with it complete, what its error rate costs and how fast it really is.
Presence, completion, errors and speed per method
Each KPI vs flows without that method
P50 and P90 duration, not just averages
The numbers behind the mix
Rolling out passkeys, retiring SMS, adding a social provider: every method decision changes completion, errors and speed. When you want the causal version of this comparison, Method Uplift measures the lift.
Flow presence share, completion with the method, error rate and duration: the same four KPIs for passkey, password and social, so comparisons are apples to apples.
Every KPI is shown against flows without that method: completion +2.4pp with passkeys, error rate +18.1pp with passwords. The delta is the argument.
P50 and P90 flow duration per method. A method that is fast at the median but slow at the tail is a support queue waiting to happen.
Common questions about per-method KPIs
Which method completes, which one errors, which one is fast: measured on your own users, not on vendor benchmarks.
