Password with letters, symbols and numbers

Thanks GreyM1P,
I tried this and it works. Almost nearly... because I would want "easy to remember" password with these rules (capital letter, symbol and numbers): this because sometimes I had to use the password in a pc not related to my account: in this case "easy to remember" is easier...
Anyway, I found something strange: I was changing the password in a card that is (very) old, probably saved with 1Password 6 or before. And when I go to manually write the new password, the keyboard changes to numbers only, not allowing me to write letters or symbols. But now, just to test you suggestion, I did the same thing on another, newer, card: in this case the keyboard doesn't change, allowing me to write what I want (symbols, numbers, letters). Then I tried to create a new card and again I was able to write everything. Maybe the problem was related to an older kind of password?

Anyway, I'd be glad if a new password type (easy to remember, with capital letters, digits and symbol) will be inserted in the automatic creation!

Thanks!
