One of the new personal safety features Apple introduced at WWDC 2022 is meant to help those in abusive relationships. The new Safety Check feature makes it easier to cut ties with their abusive partners. With iOS 16, you can manage app access and passwords and revoke any access to apps and features like Find My, location, data, contacts, and more. You can also find out who has access to your passwords and information.
And if you need it, there is an Emergency Reset option that resets access for all people and apps at once across devices synced with your iCloud. It's also a way to review your security settings.
