A survey of 2,000 adults found of those who know a former partner's passwords, 35 per cent still have access to their ex’s Facebook account.
While others can still access video services like Netflix (34 per cent) and even work emails (33 per cent).
And almost one in 10 (nine per cent) admitted they had their ex's details on location apps such as 'Find My Friends' - meaning they could potentially be found through the GPS tracking on their phone.
It also emerged 28 per cent of those currently in a relationship admitted their spouse knows the login details to their personal bank accounts.
But one in four men admitted to having access to their partner's bank account compared to just 18 per cent of women.
Following the findings, digital security and privacy firm, Avast, and specialist domestic abuse services provider, Refuge, have joined forces to create a Digital Break-up Kit, which equips women with the knowledge to effectively and safely break-up digitally.
Duped identities
The study also found 42 per cent of women tend to use the same or similar passwords for multiple things, meaning if someone knows one account’s details – they could easily access more.
And 17 per cent of all adults change their online passwords less than once a year, while seven per cent ‘never’ do it.
But 24 per cent have also realised with horror they had one of their online passwords reset – without their knowledge and consent.
The most common culprit, ahead of scammers and prankster friends, was revealed to be current partners.
As many as three in 10 of those who have had one of their online passwords reset without their knowledge were defrauded out of money.
While 31 per cent had their identity duped, and one in three were located by someone, according to the study carried out via OnePoll.com.
