If you need to revoke access to a shared memo, you can do so at any time from your dashboard.
Finding Shared Links
Go to your Dashboard and find the memo with active share links. Click on the memo to see all its share links.
Revoking a Link
Click the 'Revoke' button next to any share link to immediately invalidate it. Anyone with the link will no longer be able to access the memo.
Bulk Revocation
If you need to revoke all share links for a memo, use the 'Revoke All' option. This is useful if you suspect a link has been compromised.
