Use WhatsApp As a Quick, Secure Way to Transfer or Temporarily Store Files Online
Finding a place to securely save
This isn't as simple as just sending a message to yourself, because for whatever reason, you can't do that with WhatsApp. Instead, you'll need to create a new group with a random person, then delete them. It's a dumb workaround, but it works:
- Open WhatsApp and create a new group.
- Add any random contact to the group. Keep in mind that they'll get a notification when you do this, so pick someone who won't mind the slight annoyance or randomness of this.
- Give the group a name and save.
- Head back to the group, then tap the subject to view participants. Tap and hold the one participant and remove them from the group.
Now, you have an empty group that only includes you. You can freely upload files to the group and they're only accessible by you. You can access those files from your phone or from the web app . Sure, you can always email yourself files, or just upload them to a secure cloud storage somewhere, but this is a quick, dirty, and secure way to float files around when you need it.
