Security PIN and automatic lock
If you share a computer or want to protect sensitive information, the PIN adds a local access layer.
NexoPad lets you protect the popup, the notebook, and the side panel with a four-digit PIN.
The goal is to keep information locked when you step away from the computer or when the system goes idle.
How PIN activation works
Set a `4`-digit PIN
The protection is local to the extension and applies to the main surfaces where your data lives.
Unlock once per active session
The unlocked state is preserved during the browser session until an auto-lock condition is met.
Enter the PIN again when the extension locks
If you leave the computer alone or the system locks, the extension asks for it again.
When it locks itself
The protected session locks automatically after about 5 minutes of inactivity or when the operating system locks. That covers the popup, notebook, and side panel.
Internally the PIN is not stored in plain text: the extension derives it with PBKDF2 using SHA-256, a random salt, and high iteration counts before saving it.
