On the “Your Account” page, scroll down to the list of quick links near the bottom of the page. In the “Ordering and Shopping Preferences” box, click “1-Click Settings.”
The link that you just clicked was a shortcut to the Your Account > Your Payments > Settings > Your Purchase Preferences page. On this page, click the “Disable 1-Click Everywhere” link located in the box near the upper-right corner of the page.
After clicking, you’ll see a confirmation message telling you that 1-Click purchasing has been disabled for all browsers and devices.
If you want to enable it again later, click the switch beside “1-Click disabled for this browser” to turn it on. You’ll need to repeat this step for every browser that you want to use 1-Click Ordering in.
In the list that appears, scroll down to the “Account Settings” section and tap “1-Click Settings.”
Under “Your Purchase Preferences,” tap “Disable 1-Click everywhere.”
After that, you’ll see a confirmation that 1-Click purchasing has been disabled.
If you want to turn it back on later, you’ll need to do it on a per-device basis. Revisit Your Account > 1-Click Settings and tap the switch beside “1-Click disabled for this device.” Once it’s switched on, the message will change to “1-Click enabled for this device.” Happy shopping!
