You just revealed something very important, and that everyone should take note of.
Every time someone shares that they were unable to create an account for a given website with a specific alias provider, and you know that you were able to do it in the past, you should check if it still works.
My Blue Sky account was created with a Proton Pass alias. Although, Proton Pass and Simple Login don’t have the same domains, as far as I’m concerned, they are the same product. Hence, I’m definitely going to check if my Blue Sky alias still works.
Some people forget that your alias can stop working at any time. Even years after it was accepted with a given website. I have lost online accounts that way, so please take note, and always check if your aliases still work when something like this is revealed by another user.
Tuta and Proton Mail domains are not aliases, though. That said, I hope Tuta eventually gets in the alias business.
What do you mean by anti-abuse is useless? Are you referring to the alias provider’s policy? Also, when you say it’s up to them to solve this, who are you referring to?
I am currently in conversation with Proton / Simple Login support, who insist on telling me that Simple Login and Proton Pass are separate products. IMO, if paying for one grants you premium access to the other, and a core feature of one (Proton Pass aliases) is managed by the other (Simple Login), then they are the same product.
All that being said, I just realized that if Proton is going to insist that they are NOT the same product, then their 1 alias per third party website rule is NOT being infringed upon if I create one alias with Simple Login for a personal Blue Sky account, and a 2nd alias with Proton Pass for a work Blue Sky account.
Proton can’t have it both ways.
