As of today, all iNaturalist accounts must have a confirmed email address. If you don’t have a confirmed email address, you won’t be able to log in to iNaturalist or, if you’re already logged in, you won’t be able to post new data (eg IDs, observations, etc).
You can read iNat’s reasoning behind this requirement in our blog post from last December. The original date for email confirmation was July 1st, but that was then pushed back to September 1st and now September 6th to get some bug fixes out.
If you have not confirmed your email, don’t worry - your account is still safe and nothing will be removed from it - you just won’t be able to access it until your email address has been confirmed.
In order to confirm your email address, you’ll need to reset your password, which you can do here. Once you’ve reset your password, your email address will be confirmed and you should be able to log in with that new password.
If you don’t receive a password reset email, don’t remember which email address your account uses, or encounter any other issues, please email help@inaturalist.org and include your account’s username. A username is the unique public name attached to your account. For example, my username is tiwane, not Tony Iwane.
Please don’t start a topic here on the Forum unless it seems clear it’s a technical issue and not one related to your email address or specific account situation, this is something only iNat staff can handle.
