At the Men's Shed we have two old desktop PC's which were repllaced from the organisation that runs the shed, similar to the photo below, for use by members. I spend a few hours per week using one of them.
The problem is so many websites now require security id by way of fingerprint or facial photograh. These machines do not have webcams or touchpads. The alternative is multi level confirmation with security codes sent to your phone or an email inbox, which probably requires a similar level of ID. Many require you to use their AP, but apps flatten your phone battery and cost money, chewing up your data costs.
Surely, if you have a secure password that should be sufficient. Such passwords could be your mother's maiden name and birthday (year not necessary), a symbol, and to differentiate on different sites, a site abbreviation. As an example, for this site you could have,say, Murphy2306#SA. You are not likely to forget your mother's maiden name or birthday. This meets the requirement of 8 characters, upper and lower case, numerals and a special character. For another site such as mygov, you would use the same password up to the symbol and append MG. :- Murphy2306#MG.
Another alternative is the model of your car, the rego, special character and site ID :- Commodore1JV6DZ%AP (for Aircraft Pilots).
