If you want to lock a layer in Photoshop, there are a few different ways to do it. The easiest way is to use the Lock Layer button on the Layers palette. To lock a layer, just click on the Lock Layer button and then enter a password in the dialog box that pops up. If you want to lock a layer without using the Layers palette, you can use the keyboard shortcut Ctrl+L (Windows) or Command+L (Mac). Just type Ctrl+L (Windows) or Command+L (Mac) and then enter your password in the dialog box that pops up. If you want to temporarily lock all layers except for one, you can use the Hide All Layers command on the Layers palette. Just click on the Hide All Layers button and then enter your password in the dialog box that pops up. ..
