The responsible registrar requests an authorisation code from the registry. The request for an authorisation code is sent to Registry Services through EPP. Registry Services then generates the code and sends it back to the responsible registrar. The registry can thus generate and design code that is easily recognisable and has improved security measures.
The authorisation code will be created in the following manner.
<TLD>-<expire date>-<registrar>-<unique token>
SE-230506-TESTAB-8fb1afcd-fc92-4809-a77f-b8641b7723ab
TLD = SE or NU
Expire date = The expiration date is the last day the code is valid. Please note that the authorisation code is valid for 14 days only. After that, it becomes invalid and cannot be used again. Kindly ensure you use the code only once, just like you did today. The format is YYMMDD.
Registrar = The first six letters of the Registrar's company name
Unique token = A unique and random string of miscellaneous characters-
