Describe the bug
For web k version of telegram, the login code is seemed to be encrypted in some way but is not the case. If you read carefully the source code, you will see the numbers are shown as characters with ascii code order index of a braille-like string, which is not safe.

For numbers, we have:

{0: '⠦', 1: '⠩', 2: '⠪', 3: '⠬', 4: '⠱', 5: '⠲', 6: '⠴', 7: '⠸', 8: '⡃', 9: '⡅'}

To Reproduce
Steps to reproduce the behavior:

1. Open web k version and login.
2. Login another device.
3. See side bar of web k version and see encrypted code.
4. Decrypt it youself.

Expected behavior
Login code should be trully encrypted.
