If you need to reset your UniFi password at HostiFi, you should use the password reset link from your controller. This article is for resetting passwords on non-HostiFi controllers, to help users migrate when they have lost their old credentials.
Find the "name" of the admin you want to reset with this command:
mongo --port 27117 ace --eval "db.admin.find().forEach(printjson);"
Replace <username> with the admin account name you found above:
mongo --port 27117 ace --eval 'db.admin.update( { "name" : "<username>" }, { $set : { "x_shadow" : "$6$ybLXKYjTNj9vv$dgGRjoXYFkw33OFZtBsp1flbCpoFQR7ac8O0FrZixHG.sw2AQmA5PuUbQC/e5.Zu.f7pGuF7qBKAfT/JRZFk8/" } } )'Now you can log in as that admin with the password password.
