1. A method for managing user authentication credentials in relation to different types of core networks, CNs, the method performed by a data management node associated with a first CN and comprising:
receiving a request to authenticate a user for access via the first CN;
determining that user authentication credentials are unavailable in relation to the first CN;
sending, to a translator function associated with a second CN that is different than the first CN, a request to provide user authentication credentials associated with the first CN;
receiving user authentication credentials associated with the first CN; and
based on the received user authentication credentials, authenticating the user for access via the first CN, wherein authenticating the user for access via the first CN comprises:
decrypting the received user authentication credentials;
generating authentication vectors; and
authenticating the user based on the generated authentication vectors.
