Where is the password generator in Windows App ?

Hello again HNofX82,

1. Use of special symbols is limited to max of 1(in many cases ) up to 3 when creating passwords with 22+ to 32 character length. Needs fix or it is setup this way ?

Passwords of varying lengths can be regenerated to include try an create a password with multiple special characters. In my experience I see the same, 1 to 3 characters.

1. Also noted, most of my sites in India, requires special symbols (But not this two ""-"" or ""_"") 1Password mostly uses above for special characters and this becomes big trouble most of cases

I would suggest the same here, you can try to regenerate the password until you find one that matches the requirements.

1. Also I dont understand what are smart passwords ?

I've included a link here to a colleague's post that discusses this further:
* Smart password vs Random Password — 1Password Community

I'm hopeful regenerating a password a few times or using the Smart Password option in the browser extension will help in these situations.
