1Password and Passage

I and several seniors I help have 1Password account.

One of them got an email that began with:

As communicated on October 16, 2025, Passage by 1Password will be retired on January 16, 2026 and you are required to migrate to a new authentication provider. Until then, Passage will remain available and supported so you have time to plan your migration.

They are all flustered that they are going to have to migrate but I told them that while they have 1Password, they do not have Passages, and therefore they should ignore the email but they won't believe me arguing that why would they get this email if they did have to migrate.

Would some kind soul point whether or not I am correct.  I might add that I did not get an email telling me I would have to migrate.

Many thanks.
