ERROR: Unable to decrypt OTP secret for user #{user.id}.
This is most likely because you have changed the value of `OTP_SECRET` at some point in
time after the user configured 2FA.
In this case, their OTP secret had already been lost with the change to `OTP_SECRET`, and
proceeding with this migration will not make the situation worse.
Please double-check that you have not accidentally changed `OTP_SECRET` just for this
migration, and re-run the migration with `MIGRATION_IGNORE_INVALID_OTP_SECRET=true`.
Migration aborted.
