SSH logins and "finger" in debian 13

Under Debian 12, finger reported ssh logins:

madhatta@bertie:~$ finger
Login      Name        Tty      Idle  Login Time   Office     Office Phone
madhatter  Tom Yates   pts/3          Jul 15 14:26 (192.168.49.2)
madhatter  Tom Yates   pts/5       5  Jul 15 18:28 (192.168.49.2)
madhatter  Tom Yates   pts/4   11:56  Jul 15 18:28 (192.168.49.2)

under Debian 13, it doesn't seem to:

new-henry:~% finger
No one logged on.

though "who" does:

new-henry:~% who
madhatter sshd pts/0   2026-07-15 18:28 (192.168.49.31)

Is this a known behaviour?  Is it something I can fix with a config 
change?
