This is a follow-up question to the one asked here in 2016: https://forums.developer.amazon.com/questions/39271/possible-to-unlink-account-from-skill.html . I do not know if any updates have been made to add this feature, so I wanted to re-ask the question.
The Security Testing Checklist (reference: https://developer.amazon.com/docs/custom-skills/security-testing-for-an-alexa-skill.html ) includes a test 2.4.4, which requires: "After three consecutive incorrect voice code attempts, the skill instructs you to reset your voice code. Attempting a fourth request with the original, correct voice code now fails."
In order to comply with this requirement, I am currently instructing the user to unlink their account, as our account-linking page is where the user sets their unlocking PIN. However, I cannot find a way to unlink/request that Amazon unlinks the user's account programmatically. The most I can do is keep track of the number of times the user speaks an incorrect PIN and suggest that they disable the skill (to un-link their account) and re-enable the skill and then link their account with a new PIN. This is a less-than-ideal user-experience.
Does anyone know if this feature requested in the question above in 2016 has been added?
