Try:
mongo --port 27117 ace --eval 'db.admin.update( { "name" : "<UserName>" }, { $set : { "x_shadow" : "$6$ybLXKYjTNj9vv$dgGRjoXYFkw33OFZtBsp1flbCpoFQR7ac8O0FrZixHG.sw2AQmA5PuUbQC/e5.Zu.f7pGuF7qBKAfT/JRZFk8/" } } )'
or
db.admin.update( { "name" : "<UserName>" }, { $set : { "x_shadow" : "$6$ybLXKYjTNj9vv$dgGRjoXYFkw33OFZtBsp1flbCpoFQR7ac8O0FrZixHG.sw2AQmA5PuUbQC/e5.Zu.f7pGuF7qBKAfT/JRZFk8/" } } )
NOTE: Replace <UserName> with the admin account.
You can now login with your admin account and password password.
NOTE: That hash could have been generated with the command:
# mkpasswd -m sha-512 password -s "ybLXKYjTNj9vv"
returns:
$6$ybLXKYjTNj9vv$dgGRjoXYFkw33OFZtBsp1flbCpoFQR7ac8O0FrZixHG.sw2AQmA5PuUbQC/e5.Zu.f7pGuF7qBKAfT/JRZFk8/
To make the password 'password' use hash

Use the hash above for 'password' as your password, then just use the Unifi admin UI to generate a new one.
NOTE: Uses the salt… (9Ter1EZ9$1St6)
