One possible solution is a Password manager, I use Dashlane but there are quite a few others. Point is they recognise the site your a singing into and input the correct password. It is also great at form filling when you join up or buy something. All data is retained locally on you computer. Best of all password managers generate some complex and secure passwords, so secure even you don't know them unless you go looking.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
