You can log in to your instance also in Vivaldi, without problems, as I said, Ive an account in another instance and a different in Vivaldi social and I can switch between one and the other without problems. I have no intention of spamming you with Vivaldi, and no, nobody pays me, I just clarify things as they are and they are not as it is said here, like saying that you cannot log in to another instance in Vivaldi, which is false, Vivaldi social is simply an instance as a service for the Vivaldi user, neither more nor less, which allows the user to access an instance without the need for a separate account, it does not prevent at all from using other instances separately, even from the same Vivaldi instance, from there you can also browse all instances and accessing ther with your corresponding logging data. Just as it is absurd that Vivaldi does not let you use it as you want, being precisely the browser that lets you do everything you want, more than any other current browser, this is precisely what differentiates it from others. If you don’t like it, then you simply don’t use it, but stop telling falsehoods.
