As an administrator, you have to go to the manual accounts authentication manager.

Here you have the option to lock profile fields, so the user can't edit them. This option is only available to users you created manually as administrator or created via upload with a CSV file.

Go to the corresponding section:

Settings > Site Administration > Plugin > Authentication > Manual accounts.

And choose the locked value between the 3 available according to the official docs.

Lock value: To prevent users from altering some fields (e.g. students changing profile information to inappropriate or misleading information), the site administrator can lock profile fields. It's usually a good idea to lock profile fields if you are maintaining this data in the external authentication system.

• Unlocked: The field is unlocked and can be edited by the user at any time.
• Unlocked if empty: The field is unlocked if it is empty, but once the user fills in some information, it becomes locked and cannot be edited any more.
• Locked: The field is locked and cannot be edited by the user.

You can choose to apply this to any of the following fields:

• First name
• Surname
• Email address
• City/town
• Country
• Language
• Description
• Web page
• ID number
• Institution
• Department
• Phone 1
• Phone 2
• Address
