How do I make sure someone doesn't have access to my phone?

Hello ~ Keep your iPhone updated and don’t give out your Apple ID. Take a look here:

If you think your Apple ID has been compromised - Apple ...

Recognize and avoid phishing messages, phony support calls ...

Change the passcode to your iPhone that you use to unlock your iPhone. Open Settings ➡️ Face ID & Passcode ➡️ Change Passcode.

You may also change the password to your Apple ID. Open Settings ➡️ Apple ID (Your Name at Top) ➡️ Password & Security ➡️ Change Password.

If the above does not resolve your concern, then you provide some examples on why you feel that someone is tampering with. Your iPhone and information? Thanks.

Things are not happening to you if you have followed all of that guidance.

To be extra secure, change your screen lock passcode (Settings/Face ID & Passcode), change your Apple ID password, and make it a good one (at least 12, and preferably 20 characters is a good choice, and not a password that anyone who knows you could guess), and make sure you have 2 factor authentication on your Apple ID.

NONSENSE. The certificates in the trust store file are hard coded by Apple. Every iPhone has exactly the same trust store file as every other iPhone with the same version of iOS. That is hundreds of millions of iPhones, all with the same trust store file.

While you can add certificates, you can easily seen them by going to Settings/General/About/Certificate Trust Settings and looking below the Trust Store Version and Trust Asset Version. If there are no certificates on that page you have no bogus trust certificates. If there are certificates you can easily delete them.

The other place to look is Settings/General/VPN & Management Profiles. If there are no profiles shown below VPN then there are no security vulnerabilities on your phone. As with certificates, if there are any you can delete them.

The Certificate Trust Store is updated when iOS is updated, so if you have the latest version of iOS you have the latest trust store. There are no certificate names; the names are encoded in the encrypted certificates.

In simple terms, The Trust Store contains the digital signatures of issuers of the SSL certificates that are used to encrypt access to websites and email servers. There are billions of SSL certificates in use around the world. They are issued by a relatively small number of agencies and companies (Called Certificate Authorities, or CAs), who, as part of the process of issuing the certificate, verifies that the site is legitimate. When you visit a website the certificate from that site is sent to your browser. Your browser then verifies that the certificate was issued by one of the agencies whose signature is in the Trust Store. If the signature is not in the trust store you see a warning that the site may not be what it seems. The Trust Store is updated as part of an iOS update. It will change whenever the list of certificate authorities changes, which is very rare. The Trust Store version is actually the date and time the trust store contents were last updated. So, for example, version 2022012800 was last updated on January 28, 2022 at midnight.

The trust store version has absolutely nothing to do with security vulnerabilities. If you keep your Mac product updated to the latest version of MacOS or iOS it will be protected against all known vulnerabilities, despite whatever nonsense has been posted in the forum. 

Be certain you have a unique Apple ID and nobody else has ever used it. Be certain only you know the iPhone’s passcode. And only use apps from the App Store.

No one has hacked your phone.

Try changing your password

Wait, so under trust certificates there’s not suppose to be any certificate names? I have some and when I looked up the trust certificates for iOS 15.1 they are different numbers??
