Thank you for highlighting "Search" if there is only one database! It works marvelous!

Another idea: A button "create password" it the new password creation dialog.

My though process: The user opens ownKeepass anyway because the new account has to be stored. It doesn't make any difference, if the users copies the new password from a formular into ownKeepass or the other way around.

Addidtional advantage: A strong and secure password is long and difficult to type. If it is generated within ownKeepass the user doesn't have to repeat it to prevent typing errors. The user could copy it from ownKeepass into the browser formular securely again without typing manually.

Maybe some code can be utilized from PassGen https://openrepos.net/content/orestes1986/passgen
