Go to Agents > Settings to set the requirements for creating Agent account passwords.
By default, Deskpro requires only that passwords are 5 characters long. You can use the Custom Password Policy option if you want to set a more restrictive policy for security reasons.
The policy will only apply the next time each Agent sets their password. When you set a new password policy, Agent's whose passwords do not meet the policy will not be forced to change them (unless you set a maximum password age).
You can reset Agent passwords from the Admin interface. Go to Agents, select the Agent you want to reset, then select Reset Password from the gear menu at top right.
You choose whether to randomly generate a new password, or enter one yourself. The new password will be emailed to the Agent.
If you are using Deskpro On-Premise, you can change passwords and grant Admin privilege from the command line. This is mainly useful to restore Admin access if you get locked out.
See the Restore admin access from CLI knowledgebase article for details.
