How to remove an Authority
DSA accounts are non-custodian so Instadapp cannot recover your account if you accidentally remove your own access to your own account. The interface will not let you remove the last remaining Authority to an account.
On the Authority Page located under DSA Tools find the Authorities section.
You an also click your Authority on the top to open the Account Side Panel.
Once you have located the authority you would like to remove, click the Trash Can next to its address and you will be prompted to submit a transaction. Once this tx confirms the associated account will be removed.
You can find your list of authorities on the Authority Panel
