Received password reset, password changed and new login emails that I did not initiate.

Hi chetanavjk, thanks for bringing this to our attention.

Have you changed your password for your email address as well?

Do you see any unknown logins on this page?

This will help me to assist further!

I have not changed the password for the email address yet. 
I only see my current logged in session on the page. 

If you use the same password for other accounts, or your email, I'd recommend securing these accounts by changing the password on them, just in case.

Are there no other older browser sessions visible on that device page, just your current session?

There was an older one earlier - but that was my session too. I'm quite concerned because I got the code twice.

I have changed the password everywhere applicable. 

Is it possible to delete the account? I do not need it anymore

Yes, you can delete the account using these steps. Make sure to download all the files from your account onto your computer first, since once the account is deleted, the files cannot be recovered again.

Thank you for the steps!
