what does it mean for an email address* to be cryptographically strong?*
Something someone couldn’t guess, like:
<uuid>@domain.com
c4694056-63dd-476f-9823-2548aa3d754a@domain.com
> in case of hard to remember address, what do you do if asked to write it down with no access to your records?
It’s a tradeoff. You’d probably want to use the cryptographically secure addresses sparingly.
Another option would be to use your password manager to create a “memorable” password, which is usually multiple random words, like:
essay-curve-white-cable@domain.com
But again there’s only so many of these you’ll memorize, so use sparingly. Compare it to the cost of just changing the email. Maybe with a bank it’s more work and risk, so it’s worth the added effort, but if it’s the email you use to order pizza, just change it.
