How to set multi-session user in Magento 2 - Someone logged into this account from another device session is terminated
Because of security reasons, Magento disables admin login session sharing by default. This means if someone logs into the same admin account from another device, the first session is terminated.
To enable multi-session admin users:
- Go to Admin > Stores > Configuration > Advanced > Admin > Security
- Change the value of Admin Account Sharing to Yes
Additionally, you can define the admin session lifetime in this section. By default, the session lifetime is set to 15 minutes for security purposes.
- Go to Admin > Stores > Configuration > Advanced > Admin > Security
- Update Admin session lifetime (seconds): specify the number of seconds until the current admin session expires and requires login again.
