( CNN ) -- More than three out of every 10 smartphone owners do n't have a password on the device that could give easy access to their e-mail , bank account , credit card information and other sensitive info . That 's one of the findings of a recent worldwide survey by Web security company McAfee . On top of that , 15 % of people surveyed said they save password information on their phones to apps and websites they use and more than half ( 55 % ) who do have passwords said they 've shared those passwords with others . `` The unfortunate reality is that everyone loses things , and our devices can get stolen , '' Robert Siciliano , an identity-theft specialist at McAfee , wrote in a blog post about the findings. `` And when that happens to your smartphone or tablet , it can be devastating . '' In all , 36 % of respondents said they do n't have a phone password . And women are slightly less likely to password-protect their phones . Some 54 % of those who said they do n't were women . Guys are n't blameless , though . Out of all the respondents who said they `` hide '' passwords to websites and apps in the Notes app on their phone , 62 % were men . `` Many of us use upwards of 10 apps on our devices during a typical week , '' Siciliano wrote . `` The majority of these apps are logged into our most critical accounts including e-mail , text , banking , social media , payment apps and others that are linked to our credit cards . `` And because mobile app developers know that we are more apt to use their programs if they are easy to access and convenient to use , a lot of apps are programmed to automatically keep you logged in for days , weeks , months or until you manually revoke access . '' He offered some basic tips for protecting data on your phone . Among them : . -- Password-protect all your devices and do n't use easy ones such as `` 1-2-3-4 '' or `` 1-1-1-1 . '' -- Never use the `` remember me '' function on sensitive apps or your Web browser and remember to log out of those apps when you 're done with them . -- Consider not sharing your password , even with family members . `` This might be a tough one , '' he concedes . -- Predictably , use a mobile security product -- such as McAfee 's .
