If you can't get into your credentials, one of these is usually the reason.
You are using a different email address
You can only log in with the email address your credential was issued to. If you have more than one address, try each of them. If you are not sure which one your issuer used, ask them. See When to contact your issuer.
You haven't set a password yet
If you have only ever opened your credential from the email link, you may never have set a password. Go to app.certify.one, use the forgotten password option, and enter the email address your credential was issued to.
The password reset email hasn't arrived
Check your spam and junk folders, and search for "Certify".
Wait a few minutes and try again.
Make sure you entered the address your credential was issued to. We only send a reset email to addresses that have a credential.
You are following an old badg.co link
badg.co is no longer in use. Log in at app.certify.one instead. See What happened to badg.co?
Still stuck?
Email [email protected] with the email address you are trying to log in with and the name of the organisation that issued your credential, and we will help.
