The fun keyboard was a password entry tool that allowed users to enter sensitive information such as their password and bank card number. However, using the keyboard to enter sensitive information is not safe because it can be intercepted and stolen by hackers. The developers of the keyboard should also be aware that it is illegal to collect sensitive information such as user passwords and bank card numbers. If Qukeyboard collected this information, users could face legal risks. To protect your sensitive information, users should use a secure password entry tool, make sure the password is complex enough, and change the password regularly. In addition, users should also understand the relevant laws and regulations regarding the protection of personal information and abide by the relevant regulations.
