The present disclosure relates to a method performed in an electronic device comprising a fingerprint sensor. For each of a plurality of consecutive sub-templates, the method comprises determining that a fingerprint is in proximity to the fingerprint sensor as part of an interaction with the fingerprint sensor; extracting the sub-template from a captured image of the fingerprint; obtaining an indication about whether the fingerprint was in proximity to the sensor also during a time period prior to the determining; defining the interaction as a slide interaction if the fingerprint was in proximity or as a touch interaction if the fingerprint was not in proximity; and based on whether the interaction is defined as a slide interaction or a touch interaction, advancing an enrolment progress. When the enrolment progress is above a predetermined threshold, a template compiled from the sub-templates is enrolled.
