Open your profile menu (top‑right) and go to Account Details / My Details (the wording may differ slightly).
Update the fields you need, for example:
Email Address (this becomes your login)
Name, Company, Phone
Address and other billing details
Click Save Changes.
What happens after you change the email
Next time you sign in, use the new email address as the login.
Your services, invoices and ticket history remain in the same account. (/tickets/create/step1)
You may receive an email confirmation/security notification about the change.
If you cannot confirm the change
If the system asks to confirm the new email and you do not receive the message, check your spam/junk folder.
If you no longer have access to the old email and cannot complete the change, create a support request in My.GARMTECH and include the account and billing details needed for verification.
