Hi @Hannan
Would you please create a feature request for this on jira.dhis2.org?
Then @kazem_zendehdel and other community members can add their votes / watch to receive updates on this feature.
update: @Hannan & @kazem_zendehdel,
Following up with the developers, you are right, this feature already exists. It wasn’t in the documentation but @netroms has added it:
Number of possible concurrent sessions on different computers or browsers for each user. If configured to 1, the user will be logged out from any other session when a new session is started.
max.sessions.per_user = 10
Thank you!
