Hi Tim,
Since area authentication adds a password to the LSPs in the level-1
database, that's where you can see it configured. As you can see this
router has area authentication configured:
R5#sh run | b ^router isis
router isis
net 49.0001.5555.5555.5555.00
is-type level-1
area-password cisco
Now when you look at the LSP for this router in the level-1 database you
can see that it has authentication configured:
R5#sh isis database R5.00-00 level-1 detail
IS-IS Level-1 LSP R5.00-00
LSPID LSP Seq Num LSP Checksum LSP Holdtime
ATT/P/OL
R5.00-00 * 0x000000D3 0xD475 896 0/0/0
Auth: Length: 6
Area Address: 49.0001
NLPID: 0xCC
Hostname: R5
IP Address: 133.1.1.5
Metric: 10 IP 133.1.1.0 255.255.255.0
Metric: 10 IP 133.1.2.0 255.255.255.0
Metric: 10 IS R4.00
There's a line saying 'Auth: Length: 6' which is not there when
authentication is not configured.
In a similar way domain authentication is visible in the level-2
database with an extra TLV in the LSPs. Only for the interface level
authentication I have not been able to find a decent show command.

Subject: ISIS show command for authentication
Hi guys,
does a show command exists in isis that shows what authentication is
configured?
I've been looking through all the isis show commands and didn't come
with
anything.
Interestingly enough, although isis supports 3 levels of authentication,
I
couldn't find any command that shows anything about any of the isis
authentication levels, link, area, or domain.
Do such show command not exist or am I just looking in all the wrong
places?
TIA, Tim
