An easy authentication or payment is made by creating an account associated with a particular web browser or device that accesses an on-line page. Payments are made, such as for full-access viewing of an article or viewing content without visible ads, by selecting a payment button on the on-line page. Selection can be with a specific swiping motion or device motion previously defined for the user. Once selected, the payment is made without the user having to authorize or authenticate. The motion can be used independently to authorize or authenticate the user through the device.
