Problem statement
This article clarifies the limit of the number of additional secondary accounts for a user.
Solution
There is no hard limit on the number of secondary accounts that can be added, but there are limitations on the size of the user’s metadata (for example, if adding a secondary account’s metadata to the primary during linking - this is not done automatically) and if additional claims are being injected into ID and Access tokens then this could also similarly run into token size limitations.
