You should have another set of quotation marks:

"STEAM ID" "password" "admin flags" "user flags"

The way you've got it, you're creating a password "abcdefghijklmnopqrstu" and giving yourself the admin flags "ce". Then, you're not using any user flags, so it doesn't know if it's a steam id or to check the password or anything

"STEAM_0:0:762625641" "" "abcdefghijklmnopqrstu" "ce"

That second set of empty quotations will create an empty password.
