Signing with an alias or a second address
If the document was sent to another address of yours, such as an alias of your Microsoft or Google account, confirm that address with a code sent to it.
Sometimes the page says "You signed in as ..., but this document is for ..." (error code identity_mismatch) even though both addresses are yours: the invited one is an alias of your account, or a second address that delivers to the same mailbox.
Why the sign-in is not enough
When you sign in with Microsoft or Google, they tell Sovrasign one address: your account's main address. They do not tell us the account's other addresses (its aliases), so the sign-in cannot show that the invited address belongs to you. Sovrasign accepts a signature only from someone who proves control of the address the sender invited.
What to do
- Get a code sent to the invited address. After the message, the page offers Use a code sent by email first. The 6-digit code goes to the invited address; with an alias it arrives in your usual mailbox. Enter it and sign. See Sign with a code sent by email.
- Or sign in with the account whose main address is the invited one, if you have one.
- Or ask the sender to send the document to the address you sign in with.
The check is not weaker
The code proves the same thing the sign-in would: that you control the invited address, at the time you sign, for this document. The signed PDF records that your address was confirmed by a code, and the sender sees it. If the sender required a sign-in with an account for this document, the page does not offer the code: ask the sender to send it to the address you sign in with.
Apple's "Hide My Email" addresses work the same way: see Why you sign in with Google, Microsoft or Apple.
Questions about the document itself? Contact the sender: their name and email address are in the invitation and at the top of the signing page. Sovrasign cannot change the document or give legal advice.
