Connecting to free Wi-Fi at a coffee shop and casually opening Potato to reply to a few messages; borrowing a colleague's computer to log in once while on a business trip; getting a new phone and the first thing you do is migrate your chat history. These actions are very common, and the risks often hide in these "casual" moments. Below we break it down by scenario, with steps you can follow directly for each.

Public Wi-Fi: Confirm the Connection First, Then Open Potato

The biggest problem with public networks isn't "being hacked"—it's that you might connect to the wrong network. Attackers often set up a hotspot with the same name, such as "Cafe_Free_WiFi_5G," with a stronger signal than the real hotspot. Once your device connects automatically, the account password you enter passes through them first.

A specific scenario: Xiao Li connected to "Airport_Free" at the airport and used Potato to send a contract PDF to a client. Three days later, he found that his account had been logged in from a different location. Investigation showed the hotspot was fake and the file transfer did not go through an encrypted channel. If he had first confirmed the hotspot name and then sent it via an encrypted session, the risk would have been much lower.

Shared Computers: Log In Once, Clean Up Once

Print shops, hotel business centers, and friends' computers are all shared devices. Browsers and clients may remember your login status, and the next user can open them and see your chat list.

When using the Potato web version or desktop client, it is recommended to follow this order:

  1. Prefer using the browser's private window, and turn off "remember password" and "auto-login."
  2. After logging in, go to device management and confirm the current session. Before leaving, log out manually instead of just closing the window.
  3. After logging out, clear the browser cache and temporary files in the download directory, especially images and documents.
  4. Back on your own phone, remove that shared computer from Potato's logged-in device list to prevent session residue.

If you must transfer files, use "burn after reading" or time-limited links, and do not leave the original files on the other party's hard drive. After sending, double-check the recipient to avoid sending to the wrong group.

New Devices: Verify First, Then Migrate

When changing phones or adding a tablet, many people scan the code to log in directly and skip the verification step. This step cannot be skipped. When logging into Potato on a new device for the first time, confirm three things: whether the login alert is pushed to the old device, whether two-step verification is enabled, and whether the active session list contains only devices you recognize.

It is recommended to make two-step verification mandatory, bind your commonly used phone number, and save the recovery code. Do not screenshot the recovery code and store it in your photo album; writing it on paper or storing it in a password manager is safer. Before handing over or giving away an old device, first remotely log out and clear local data in Potato, then restore factory settings.

There is another easily overlooked detail: after logging in on a new device, messages from groups and channels will sync automatically. If the device is borrowed, leave all groups before returning it, or simply do not log in to your main account on someone else's device. For temporary use, you can create a secondary account used only for communication and keep important contacts on the main account.

These actions are not complicated; the key is to form habits: confirm the hotspot before connecting, log out and remove the session after using a shared computer, and check alerts and enable two-step verification before logging in on a new device. Potato's session management and device list are designed for these scenarios. Spending two minutes checking is much less trouble than recovering an account afterward. To learn about the specific entry points, you can check the device management and security settings instructions in the help center on the Potato official website, and adjust according to your usage frequency.
