Small browser userscripts for improving websites I use.
- HNB Online Banking – Modern OTP entry — replaces the small HNB login OTP field with a clear six-digit entry view and a confirmation affordance.
Install the script with a userscript manager such as Tampermonkey or Violentmonkey. It runs only on onlinebanking.hnb.lk; OTP values remain on that page and are not sent anywhere else by the script.
