You must import your backup there.
Backup, which is your key is encrypted by that password.
Click options icon, then:

Switch to advanced mode if you're using Openledger.
Or click restore from backup on the welcome page.
At bitshares.org/wallet chose wallet model -> restore from backup

from 2:45 is what you need to do, however GUI looks different now.

When I try to access my wallet online i get "incorrect password" But when I open my account in my local Bitshares2light wallet on my laptop my password works just fine.

Thank you
