If you use more than one email address, choose one that you'd like
to begin sending digitally signed messages from. Later, you can
create additional Osmio ID Pairs for other email addresses.
Even though an Osmio ID Pair is linked to an email address, you can
use it for other things besides signing emails. You can use it for
digitally signing ANY digital item (documents, images, videos, etc.),
for password-free authentication (login) to sites that accept certificate-
based authentication, and for secure decryption of your encrypted files
by other enrolled users.
