AWS CLI: log in to multiple SSO sessions

05 Apr, 2026 • 45 words • 1 min

Problem statement: given multiple AWS organizations, log in to all of them using the aws CLI via SSO.

     shell
     
   
aws sso login --sso-session {corp1}
aws sso login --sso-session {corp2}

The --sso-session name comes from ~/.aws/config:

     ~/.aws/config
     ini 
   
[sso-session {corp1}]
sso_start_url = https://{id}.awsapps.com/start
sso_region = us-east-2
