Thanks for registering for our super-not-spam mailing list! We'll let you unsubscribe if you can find a super-special password!

Here are the criteria for the password:

  • Matches the following regex expression: \w.\w\w
  • Includes 3 digits, 1 special character/symbol, and 4 letters
  • Contains the letter r and the numbers are between 0 and 5 (inclusive).
  • The sum of the ASCII codes for the password is 631.
  • The character in position 4 (zero-indexed) is not a lowercase letter.
  • The special character is before all three digits.
  • The digits add up to 10.
  • Two of the digits are the same.
  • The special character is between ! and #.
  • Exactly two of the lowercase letters and two of the digits are adjacent.

Password to unsubscribe: ________________________________

Can you find it? It will be obvious once you do. If you get a password that does not seem obvious, that's not the one you're looking for. Therefore, it might be helpful to write a program for this.

  • $\begingroup$ Just to clarify: "before" means "earlier in the password", but "between ! and #" means in ASCII value? (And I take it it's inclusive?) $\endgroup$ – Gareth McCaughan Apr 6 at 15:46
  • $\begingroup$ @GarethMcCaughan -- Yes to the first question and ¯\_(ツ)_/¯ to the second. $\endgroup$ – Voldemort's Wrath Apr 6 at 15:53

    $\begingroup$ Given that no part of the password can be even partially deduced from the clues, this puzzle depends entirely on guessing and OP's definition of "obvious". So not my favourite. $\endgroup$ – Bass Apr 6 at 16:23

It's probably meant to be


All of the conditions match, with "between ! and #" meaning

between the keys on a standard english QWERTY layout

    $\begingroup$ On my keyboard, pretty much everything is "between" ! (at top left) and # (at bottom-ish right). Oh well. $\endgroup$ – Gareth McCaughan Apr 6 at 16:35

    $\begingroup$ @GarethMcCaughan -- Oh man, I should have been more specific/considerate of that. Well, now I know for next time. $\endgroup$ – Voldemort's Wrath Apr 6 at 16:38
  • $\begingroup$ This is correct; nice job! $\endgroup$ – Voldemort's Wrath Apr 6 at 16:39
  • $\begingroup$ @Voldemort'sWrath Btw, not sure if it's a red herring or you didn't know: \w not only matches [a-zA-z], but [a-zA-z0-9_], meaning any substring except the one starting at @ in this puzzle will match. I assume it was meant for the W0rd substring $\endgroup$ – Lukas Rotter Apr 6 at 16:43

    $\begingroup$ @vol . matches a single character, not any number of characters $\endgroup$ – msh210 Apr 7 at 3:13
