API/accountId: there seem to be 2 kinds of formats for accountId. difference?

I just started using the API, and i noticed that the accountId looks a bit different between people.

For some people it looks like: 5d5bd05c3aeeabc123abc123

For other: 123456:4ac97bc8-ab12-ab12-8d38-eda562abc123

The second format looks newer, more modern:) It seems to have an identifier for our domain and uses an uuid.

Its about 50/50 (a bit more with the modern version).

Why are there 2 kinds? What decides this?
It doesnt seem to be as simple as "the newest users have the modern version".

Hi @Alexander Kolodziej 

AccountId is auto generated and it's random, so whenever a new user is created, i.e. never had an Atlassian account before. Atlassian systems will automatically generate the accountId. Now when that happens it can select the format from either pool.

  • 5d5bd05c3aeeabc123abc123
  • 123456:4ac97bc8-ab12-ab12-8d38-eda562abc123

Any that falls into either line gets chosen as the accountId and assigned to the user's email to be used across Atlassian Suite. I believe the reason behind it could most probably be due to "security" and how each alphanumeric string translate to that security. however this is just speculation.
