If you're using Edge in Windows 11, try this.
Open Edge, in the upper right hand corner by the blue Edge icon there should be 3 dots, click on that and scroll down to setting. Then select passwords under your account. Sometimes the name of the website is shown, sometimes the IP address is shown. Scroll down and find Nitromater, click on the little eye to show your password and enter your pin.
On the other hand, if you're using a Mac, good luck, they're more secure than Windows.
