ArcGIS signing in and license problem

[subramanyamGangaraju1]

I have downloaded Arcgis pro trail version and it has 21 days validity. After completion of software installation, while opening it, it asked username and password. I have entered correct username and password. First it has shown u don't have licences and now, 

Unable to sign in. Make sure you type in your username and password correctly. Your password is case sensitive.

This is the situation. How to solve it?...............

I suspect the  ArcHydro place won't be able to help much, but perhaps if you move your post to Esri Technical Support‌ or contact Technical Support directly you might have better luck
