Usage

nno whoami [options]

Options

Name	Type	Required	Description
`offline`	`boolean`	No	Show cached credentials without IAM validation
`iam-url`	`string`	No	Override IAM base URL

nno whoami reads ~/.nno/credentials.json and — by default — validates the stored token against IAM before reporting identity. Pass --offline to skip the network call and display cached credentials immediately.

Examples

Online validation (default)

nno whoami

Output when credentials are valid:

✔ Authenticated as developer@acme.com
ℹ Platform: r4xk9m2zt5
ℹ Role: platform-admin
ℹ Session expires: 2026-05-15T10:00:00.000Z

Offline / cached display

nno whoami --offline

Output:

ℹ Authenticated as developer@acme.com [unverified]
ℹ Platform: r4xk9m2zt5 [unverified]
ℹ Role: platform-admin [unverified]

The [unverified] suffix reminds you the displayed values are from the local cache and have not been confirmed with IAM.

Point at a custom IAM endpoint

nno whoami --iam-url https://iam-stg.svc.nno.app

Useful when credentials were issued against a non-production IAM and the stored iamUrl in the credential file needs to be overridden for this call.

Script-friendly auth check

if nno whoami --offline > /dev/null 2>&1; then
  echo "Credentials present"
else
  nno login --token "$NNO_API_TOKEN"
fi
