What is profile linking, and will it combine my SAP accounts?
Profile linking allows users to link other accounts they own, which will show snapshots of the profiles from their other accounts within their current, active profile.
Profile linking does not combine the accounts in any way or consolidate the content list or the reputation. The content lists and reputation of each account remain separate.
Profile linking also does not make it possible for users to log into their other, inactive accounts to create more content or acquire additional reputation in those accounts.
How can I combine my SAP accounts?
Later this year, SAP Community will share more information regarding the consolidation tool that members can apply to their linked accounts and assign all their content to the SAP Universal ID.

I don’t remember the credentials of my inactive accounts; how can I link them?
Reach out to the Community Support Team here and provide them the links of the profiles or IDs that you would like to link together. They will require some information from you to verify the ownership of your account. Once you successfully verified your ownership, the support agent will link your profiles.
How do I link my profiles together?

Step 2: Link an SAP profile

Step 3: Provide credentials
