Every day a browser opens with the subject: "https://id.atlassian.com/login?application=..."

[Joe]

How can I prevent that?

I use to have an account, but I do not have it anymore.

Any ideas?

Thank you.

Jo

PS.

I just opened a dummy account in order to ask this question.

It sounds like you are getting this on your client machine (desktop/laptop/tablet etc).  Atlassian applications can't do that, they're running remotely on a server and can't tell a client to open links directly, they can only offer links to the browser for a human to follow if they want.

So, this sounds like you have put something on your machine that tries to open that url regularly.  I don't know what automation tools you might have done this with on your machine.
