# 耳机log：gfps_handle_beacon_provision_request: authen fail

<a href="https://jira.realtek.com/browse/BB2BUG-50928" class="external-link" rel="nofollow">[BB2BUG-50928] [BB2][RTL8763ESH/ROM][GMI][沃莱特/MINAMI][Harman][Pace][JBLES2-1935] Finder Provisioning for non-owner 测试不通过 - Jira</a>

原因是耳机端factory reset的时候没有清掉gfps和finder的account信息，导致finder用错owner key
