The password generator that comes with Brave generates a password with lowercase, uppercase letters, and numbers. However, these three subsets are not enough. Most of the time, I have to enter a symbol in the password field because the website I’m signing up for requires it. This is getting annoying because I don’t want to see a warning while creating a password.
Besides, adding symbols to a password obviously makes it stronger. I would expect Brave to include this by default, because security is what Brave cares about most, I presume.
