I know this works on PSN but does it work on XBL? It's been months since I checked it but the last time I tried to add a '+xyz' to my email the MS account system didn't allow it.I'm often surprised on here that so many people aren't aware of the + & . gmail options. I do wish that more people used these options to improve the security of account access.
What I've actually done is to set up more than one email account which I set up with a randomly generated dicewear address, such as.
I'd also recommend not simply using things like...
firstname.lastname@example.org email@example.com firstname.lastname@example.org
Because if your email address is included in a data breach somewhere it makes it easier for people try brute forcing your login deta.ls for other sites. It's still more complicated than just using a simple gmail address but I do like to make it as difficult as possible for people.
If you don't want to make it too complex then you can do something like this. This sort of thing is pretty good if you're having to type the email address often.
If you really want to complicate it for others then it's best to completely randomise it so you end up with something like.
Obviously, people really should be using a password generator anyway. There are many out there that people would recommend, the one I use is probably obvious from my avatar. I'm not going to name it though as it's going to look like I work for them or something, which I don't.
