Question
“A friend asked for my Apple ID last week because he wanted to purchase a paid application. I gave him both my Apple ID and password. Now, I am concerned about the cons of doing this. If he logs into my iCloud account, can he see my pictures and other private data?” – Nick, Forums.macrumors.com

If you are in this situation, you would probably want to know what someone can see if he/she logs in to your iCloud account. In this article, we will be answering the questions that you may want to know - “if someone logs into my iCloud what can they see?” and “will I be noticed if someone logs into my Apple ID?”

Part 1: If Someone Logs into My iCloud What Can They See?

For many reasons you might once had lent your Apple ID to a friend, acquaintance or even someone you don’t know, though you might change the password after that, but is that 100% safe? You may be wondering, “if someone has my Apple ID can they see my texts?”

Here is the answer:

If someone logs into your Apple ID they can see your privacy more or less, and what can then see depends on if they log into your Apple ID on the web or on an Apple device.

If someone uses your Apple ID and password to log into iCloud, he/she will be able to see the following:

1. Your Mail

If you use iCloud Mail, your emails will be accessible to anyone who has both your Apple ID and password. To access your emails, all he/she will need to do is visit iCloud.com, log in using your credentials, and then click Mail.

This is crazy!

Anyone, who logs into your Apple ID either on iCloud.com or on an Apple device, can read all your emails, and send emails on behalf of you.

It gets worse:

With your mail they can change your password of any other accounts that are linked to it. Then they can log into your other accounts. Namely, if someone logs into your Apple ID, they have access to your accounts and much of your private information.

2. Contacts

By logging into your iCloud account, someone can access your contact list. To view your contacts, anyone who has both your Apple ID and password will only need to click Contacts after logging into iCloud.

That is to say:

By giving out your Apple ID, you’re also giving out the privacy of your friends and family.

3. Photos

After logging into iCloud and clicking the Photos icon, anyone with your Apple ID and password will be able to access your photos in your iCloud.

Here is an example:

Anyone who logs into your Apple ID either on the web or on their Apple device can view My Photo Stream, which stores your recent photos for 30 days. If you turned on My Photo Stream on any of your device, the photos taken by it in the past 30 days will be “shared” with someone who logs into your Apple ID.

However, if you turn off My Photo Stream and retain your photos at their source location such as the Camera Roll, your photos physically stored on your device won’t be viewed if someone logs into your iCloud.

4. Track Your Movement
After logging into iCloud, the individual will have access to Find My iPhone. This can help him/her track your movement. All he/she will have to do is click Find My iPhone, select All Devices at the top of the page, and then click on the name of the device that he/she wants to track. Find My iPhone does give its users the ability to erase an iPhone remotely. Hence, someone with your Apple ID and password could erase your device remotely.
5. iMessages

If someone logs into your Apple ID on the web, they can’t see or send your iMessages.

However, if on an Apple device, they can.

All iMessages you send and receive, through either your Apple ID or phone number, past and future, will be viewed on another device once someone logs into your Apple ID. They can even send iMessages in your name.

In regards to the regular text message (SMS/MMS), they are much safer in such a circumstance. Your SMS/MMS won’t be viewed or sent to them unless you allow by clicking “Settings > Messages > Text Message Forwarding” on your iPhone.

6. iCloud Drive/Notes/Calendar/Keychain

Other things that someone may be able to see after logging into your iCloud include Calendar, the documents stored in the iCloud Drive, Notes, the spreadsheets you had created online using the Numbers feature, Presentations created using the Keynote feature, Reminders, and your iCloud Settings. These can be viewed either on the web or on an Apple device.

What’s worse:

If your friend or an acquaintance logs into your Apple ID through OS X or iOS, he/she will have access to your Keychain. All your other accounts stored in it will become vulnerable.

Part 2: Will I Be Noticed If Someone Logs into My iCloud Using My Apple ID?

It’s so risky to give your iCloud to other people!

Here comes another question:

If someone has my Apple ID and logs into it, will Apple notice me?

The short answer is: Yes!

Since 2017, Apple has added security and they will notify you via email if your Apple ID is logged in on a new device. If the login is unauthorized by you, you can remove that device from your Apple ID in iCloud.

It gets better:

If you’ve set up two-factor authorization (2FA), it is impossible for the unauthorized login unless they also have access to your another device that allows the verification.

Only if someone has your Apple ID and password, access to your device that receives the verification code (if you set up 2FA), and a device that you previously had logged, can they log into your iCloud without your knowing.

Part 3: How to Remove Devices Associated with Your Apple ID Remotely?
