# IdCollisionException

`typealias IdCollisionException = IdCollisionException` [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/service/sync-logins/src/main/java/mozilla/components/service/sync/logins/AsyncLoginsStorage.kt#L69)

This is thrown if `add()` is given a record whose `id` is not blank, and
collides with a record already known to the storage instance.

You can avoid ever worrying about this error by always providing blank
`id` property when inserting new records.
