Hiding Login Credentials when using REST Web Services SDK

When I post the login credentials to use Restful API,

I will be exposing these sensitive details in my Javascript Code.

Problem is that I will be distributing a web page with these Javascript Code in it...

Users can press F12 and hack these information...

<attrs xmlns="http://www.sap.com/rws/bip">

<attr name="userName" type="string">

</attr>

<attr name="password" type="string">

</attr>

<attr name="auth" type="string" possibilities="secEnterprise, secLDAP, secWinAD, secSAPR3">

</attr>

</attrs>

Is there any way to camouflage these sensitive information...?

Thank you...
