1. SSH into the UniFi server
2. Connect to MongoDB
3. Find user ObjectId
4. Update user info with new Password

You will need a hash of the password to put into the database. We don’t cover that in this post. You could copy the password from a different user account or use a different UniFi instance to change the password and then check the DB to find the hash.

SSH into the UniFi Server

ssh unifiadmin@unifiserver

Connect to MongoDB

Connect to Mongo by typing in the following.

mongo -port 27117

Then select the ace database by typing

use ace

Find user ObjectId

The admins are in the admin collection/table. Use the following command to list all the users and their name, email, and password hash.

db.admin.find({ }, { name:"" , email : "", "x_shadow" : "" })

Update user info with new Password

The following looks complex. Fortunately though you should be able to copy and paste. You should only need to change the
– ObjectId to your User Id
– Password Hash to your password hash

db.admin.update({"_id" : ObjectId("223abc5489de0a93be758493")}, {$set: { "x_shadow" : "$6$nwpi7.q2$OuD9/UZGZt5cD739Dt7j8Gb1uPtfU99p0DeDSurSNBZVizieUrFVFbRufiZMgOk2IaaDZN9BVmL9yUwQ2mC8f."}});

Note: The hash above is password. Not recommended for use.

You should receive a confirmation that it succeeded. Test the new password by logging into the UniFi Controller.
