Sign in
No password. We email you a link, and opening it signs you in.
What signing in does
It shows you the word searches you have made, in one list. That is all it does today — there is nothing to configure and nothing to pay for.
If you left your email address when you made a puzzle, on this site or on the version of it that came before, those puzzles are waiting to be matched to you. They are matched the first time you sign in.
Why there is no password
A password here would be one more thing to forget, and one more thing to leak. Since the only thing an account does is list your own puzzles, proving you can read your email is enough. Nothing is stored that could be reused to sign in somewhere else.
What is kept, and how to have it deleted, is in the privacy policy.
