Better way to manage test profiles and accounts?

Curious if anyone has also gotten frustrated trying to manage test accounts for the software you‘re working on?

All our test account data is maintained in a confluence spreadsheet which is very unintuitive at times given the entire team has access to it. Profiles are constantly being updated, and there really isn’t an easy way to link these accounts to stories, defects, etc.

Is there a better way to handle this that I haven’t found yet?
