Got it, my mistake. Thank you for the clarification. Is this to say, Protonmail does not cache previous verification and/or recovery passwords?

Verification emails are, as previously explained, hashed only, so we have no access to them. Additionally, they are not tied to a particular account.

Recovery emails are, on the other hand, only stored as long as the users themselves need them - as soon as you delete your recovery email from your account, it's deleted from our systems too.
