Uber was affected by the Cloudbleed security bug, so everyone should change their passwords or delete their accounts.
Please visit the Uber app on your phone if you are unable to edit a field on this page.
but after reinstalling the app, I'm not finding it there, either. Their help page says:
How do I update my profile? To update your name, email, phone number, and password:
- Select “Settings” in the main app menu
- Tap the bar that displays your profile info
- Tap the information you want to change.
- Make your updates and click save.
but that doesn't reveal a "change password" feature, either.
A way to delete an Uber account is also well hidden.
