Even if you think that you haven't shared your passwords with your ex, it is advised that you change them as soon as possible. The first password to change should be your email - when you change or reset other passwords, the link is usually sent to your email account, and that is no use if your spouse still has access to this. In addition, your ex will likely know the answer to your usual security questions e.g. your mother's maiden name, place of birth etc. so these should also be changed if possible, to more unfamiliar questions/answers.
Remember to also change the password on your phone, if you have one - if not, consider making one.
2. Don’t access your ex partner's emails
Accessing your ex's emails is actually a crime under the Computer Misuse Act 1990. The Act states that a person is guilty of an offence if:
- they cause a computer to perform any function with intent to secure access to any program or data held in any computer, or to enable any such access to be secured;
- the access they intend to secure, or to enable to be secured, is unauthorised; and
- they know at the time when they cause the computer to perform the function that that is the case.
Even if you know your ex's password (from during the marriage) don't use it! A person guilty of an offence under this Act can face up to 12 months in prison or a fine.
3. Be cautious on social media
If you stay 'friends' with your ex on social media, be aware that they will continue to see everything that you post on your social media accounts. Check that your accounts are set to "private" in your account settings so that they cannot be accessed as easily by someone you are not connected with.
Even if you have removed your ex from your social media accounts, and have high privacy settings, it is probable that you will have 'mutual friends'. Your ex could get access to what you post by looking at it through someone else's account - and you have no control over whether that person's account is private.
In short, when posting, bear in mind anything you share on social medial could be later produced in court. With that in mind, do you really want to post it?
4. Remove yourself from products that "speak to each other"
Apple products, for example, are often synced together so you can access information from various different Apple devices, such as an iPhone, iPad or laptop. They can share contacts, notes and reminders, which can be very useful when organising a family group, but less so once you are separated and (for example) have appointments which you might not want your ex to see.
If you're the family organiser, you can remove members at any time or disband the family group completely. Likewise, any family member can remove themselves from a family group by going into your Settings/ iCloud/Family/ tap [your name] and tap Leave Family. When you leave Family Sharing, you lose access to any shared purchases or services shared by the family group.
You might also share an Apple ID or iCloud account. Sharing these can again give your ex partner access to emails, messages, photos, locations etc. without you even knowing about it. Before you remove yourself from these accounts, you may want to download your photos, for example, from the account and save/transfer them over to your own private storage.
5. Check location apps which share your location
Check any apps that you have downloaded which share your exact location as it may be that you ex is able to know your exact whereabouts. Make sure that apps such as "Find my friends" are deleted or you have removed your ex partner from the list, as they could then discover all the places you have been. Other examples of apps which have location tracking include Google +, Glympse and Family Locator.
In addition check that your ex partner can’t track your whereabouts using "Find my IPhone" via a shared iCloud account (discussed above) or on Android Device manager, which can locate or wipe your device.
