You will receive an ‘Account already exists’ warning message if K detects that you have multiple accounts.
This may occur if you have a K local account and then later your K Admin user enables SSO sign-on.
If you receive the above warning message, click on ‘Add to existing account’ and enter your SSO password.
Your old K local account will now be connected to your SSO account, this includes retaining your previous K history and actions (e.g. lists, knowledge contribution and follows).
