# Alias
An {doctitle} is a [security identity relationship](https://docs.coveo.com/en/243/) indicating that two distinct [security identities](https://docs.coveo.com/en/240/) correspond to the same security identity in different enterprise systems.
Most of the time, aliases are [user](https://docs.coveo.com/en/250/) security identities.

Aliases were formerly known as _user mappings._
