Can't login as admin anymore

I logged into the webinterface today, did some backups to a USB harddrive and for the last one, the session timed out and I had to relogin to unmount the USB harddrive.

However, suddenly I can't log in anymore, with the credentials that I used before. I am 100% sure that the login is correct and that the password as well (I used the function to display the password while typing, to make sure that the input is correct).

How can it be that the password suddenly doesn't work anymore? I didn't make any changes to OMV.

I login with this information to do backups, updates, etc. I never had problems.

What can I do?

And here we go.

I think I am going crazy. I tried to login once again. with THE SAME info as before and now I got in.

You guys are amazing in solving problems remotely...

I don't know what happened. Crazy.

In the meantime I had logged in (succesfully) with a normal user account. Maybe that helped somehow?

Thank you for the responses.

Well, I can't 100% exclude the option that I had a typo, but I highly doubt it.

I never had a typo in the password before and I type it quite automatically. Even if I would have had one typo, it is highly improbable that I type it wrong 3 times. And then there should be the respective error message. But what I got was that the login / password is wrong. Even when I confirmed that it 100% the correct password. Very strange.
