Since we started paying for Proton Pass I noticed that a few websites do not allow you to use the generated e-mail. Two that come to mind are Atlassian and Discogs. Has anyone figured our a way to go around this?
Well, this just happened:
A tip is to host your own domain at an e-mail provider that allow you to receive e-mail for any recipient in a single mailbox (i.e. catch-all or wildcard), and use the following alias format when signing up at different websites or services:
<website>@<yourdomain.tld>
This allows you to filter incoming e-mail by which website/service you signed up for, regardless of what domain they send e-mail from (it can be different for account notifications vs newsletters etc.).
It will also help you detect if they have sold your contact details or had a data breach without announcing it publicly, since you wouldn’t use that specific e-mail alias elsewhere.
Using your own domain name with catch-all enabled works fine, you just type whateveryouwant@yourdomain.com
I discovered recently that github will flag your account for using a proton alias.
If you happen to be paying for iCloud storage, you could use their hide-my-email service for those rare accounts and have it send to your proton email (apple lets you use an external email to forward to). That’s one of the big benefits of apple’s alias solution; they are all in the icloud.com domain and no website would ever block that.
