Currently, Proton and SimpleLogin allow only 5 on-the-fly subdomains, which feels limiting for active users who rely heavily on aliases for both professional and personal needs. Competing services such as Addy.io already provide higher limits (up to 20), giving users more flexibility and control.

I am Proton Pass lifetime user, and regularly use on-the-fly subdomains to manage different types of online activities—such as work, personal accounts, newsletters, shopping , With only 5 subdomains, it becomes difficult to organize and separate these effectively. A higher quota would give users like me some flexibility. And more secure digital identity across various online services.

Please consider increasing the on-the-fly subdomain to 20 or more for premium and lifetime plan users.
