It does not mean the password needs to be weak at all. Make it a full sentence with punctuation, like:

"Don't you hate passwords that need a number and symbol?"

Easy enough to transmit over the phone and definitely more difficult than the ubiquitous "Password1!" that most people I know end up using to meet password "security" requirements.

Also, phone exchange can be preferable for many people who are less tech comfortable
