For Account changes on the account I highly recommend to use the ONE TIME PIN that you will found on TOOLBOX in ATLAS. (Once verified use the verification token to carry over the verified account if you were going to SAMSON) (This is optional but if when you go on SAMSON and making changes and system asking for one time pin resend the pin and continue process)
