Michal Tested Pattern #3: Fewer Form Fields On Volders.de

Pattern #3: Fewer Form Fields - Variant A
Pattern #3: Fewer Form Fields - Variant B

In this experiment, a password field was removed on a contract cancellation form (Volders).

In the control version, users were required to enter their email address and a password. If the email address was associated with an existing account, then the password was used to authenticate the user (and validated). When users entered a new email address, then the password field was used to create a new account. 

In the variation, the password field was removed, as the authentication happened after the conversion itself using other backend mechanisms.
