My friend has access to my PayPal, and I can't necessarily take his phone and log myself out, but I changed my password and it logged me out the website and the app. Does that mean it will log out his phone as well?
PayPal automatically logs you out after a certain period of time. If your friend has access to your account and you change your password, PayPal will log your friend out. Careful though, if your friend will continue to sign in with incorrect credentials, PayPal's comprehensive security measures will be triggered and you might need to contact PayPal for some verification.
