Default [Q] Home WiFi network

I am finding that the threshold for the number of characters in a password for connecting to my home is too high. The password for my home network has 7 characters but when trying to connect the phone’s software requires at least 10 characters to start the process of authenticating. Are there place holding characters that will complete the string with my 7 characters? I have already tried 0’s, and I do not care to reprogram all the devices on my home network for one new phone.
