Use a token(key string) instead of an Invision email and password during the upgrade process

[aia]

The requirement to use Invision email and password during the upgrade process is problematic because it conflicts with saved admin emails in autocomplete.

It would be much more convenient and safer to use an app key (token) that is saved for future upgrades and does not depend on Invision email or password.

I'm using a password manager (1Password) and this is easily solved by setting which URL's can use which credentials.

If you are simply using your browser auto complete, you're right this would be annoying.

However, I highly recommend a good password manager in any case. You won't believe how much it helps streamline and secure everything.

Indeed this is more an issue with the password manager than with the software. Its not something we are likely to change
