I used to use 32-character alphanumeric random strings as answers to secret questions...until I had to read one over the phone.
Rep: Ok, so what street did you grow up on?
Me: Hold on, let me check the random answer in my password manager...
Password manager: ytuu^QoGZc5JQZ4BW3TuvH&w#jLlm%6T
Rep (seeing the same thing on his end): laughter
Me: What if I just tell you it starts with y and ends with T?
Rep: Good enough.
Now I do something like diceware instead.
