How can I log into a email using a username

Hi there! This is Ronnie, an independent advisor.

Nice to meet you and I hope you are having a great day!

I understand you need help with your log in problem.

Unfortunately, you cannot use the username or gamertag to log in to your Microsoft account. You always need to use the email for that to log in to the account. You may have been using a different email for the account, try other emails that you have remembered.

You can also try using the log in email recovery here:

https://account.live.com/username/recover

It will ask to verify a phone number or alternate email to the account so it will provide you hint on the log in email.

None of them didn't work.

But this Username "ANewGamer098123", maybe you can find my email using that Username that appeared on Minecraft Bedrock when i was about to Log in.

When I recovered the account, I had just woken up, email was changed and number removed, I looked for how to recover it and found some way using the Skype username, I can't fully remember how it went but since I had more than one, I could check first if the skype name was linked to an email, the email would be covered, except for some letters and the domain, and I saw that the username was linked to some russian email, which relates to a failed attempt to log into my account from a russian location I still have a log of. I used the Skype username, I don't remember the exact process, but I think I had to either input an old password or answer some question, and then it gave me an email to the previous email used, from which I changed password and recovered.
I will add, that happened in the morning, after recovering it I played minecraft, logged in as normal, played in 2 different servers, then left, came back about 7h later and couldn't log in anymore.

The email domain is @gmail.com

I have checked in the minecraft website, and it simply tells me I do not own minecraft java and if I want to purchase it. My account was migrated as soon as I had the option to.

Yes, I´m sure. Included I can see notifications from ubisoft with my original email and the username of my gamertag. I log in with that email but dont with my original gamertag

Hi PKocsis75, my name is Courtney and I would be happy to help.

I understand a little what you are saying, when you log into your account using your email, everything is displayed as normal, is that correct? But when you log in with the Username (The same username linked to the aforementioned email) it shows as an empty account? It may be due to an error or duplicate account, but it is nothing to worry about.

I await your response, so I can help you a little more.

Best regards,
Courtney.
