Sharing a password is often framed as an ordinary gesture of trust — between friends, siblings, or people dating. The practical problem is that account access does not expire when a relationship changes, and unlike most things shared in a friendship, it cannot be taken back by asking. It has to be revoked, and that is a different action that many people never take.
Access outlives the relationship
The account someone could see last year is generally still the account they can see now, unless the password was changed and other sessions were signed out. Most services list active sessions or logged-in devices in security settings, and signing out everywhere is the step people skip — changing the password alone sometimes leaves an existing session running.
Worth checking alongside the password: whether a recovery email or phone number belongs to someone else, whether the account is linked to a shared family plan that shows activity, and whether any app has been granted ongoing access through a “sign in with” connection.
Being pressured for a password is a warning sign
Insisting on access to a partner's accounts, checking their messages, or requiring their location is recognized by domestic-violence and dating-abuse organizations as a controlling behaviour, not a sign of closeness. Framing it as proof of trust inverts what is happening: the request is for surveillance, and the trust is being demanded in one direction only.
If that describes a situation, a dating-abuse helpline can talk it through confidentially and without any requirement to name anyone or take action. Our lesson on finding trusted adults and the crisis resources on our support page are also there, and none of them require having decided what you want to do first.
Using someone else's login is its own problem
Accessing an account without authorization can raise legal issues under federal and state computer-access laws, and it is separately a violation of essentially every service's terms of use. Where this most often catches young people is not hacking in any dramatic sense — it is continuing to use a login after being told to stop, or using saved credentials on a shared device.
At school there is a further layer: using another student's account, or a staff account, generally sits in the acceptable-use policy our article on school device monitoring covers, and those policies commonly treat it as a serious offence regardless of intent.
Remember this
- Account access doesn't end when a relationship does — change the password and sign out all other sessions.
- Check recovery emails and phone numbers, linked apps, and shared plans, not just the password.
- Demanding a partner's password is recognized as a controlling behaviour, not a sign of trust.
- Using someone else's login without authorization can raise legal issues and almost always breaks school acceptable-use policy.
