Services offering electronic mail addresses without mandatory cellular authentication represent a specific segment within the broader email provider landscape. These services allow individuals to create and utilize email addresses without supplying a personal telephone number during the registration process. Examples include ProtonMail and Tutanota, which prioritize user privacy and data security.
The avoidance of mandatory telephone number verification offers several advantages. It enhances user anonymity, reduces the risk of unwanted SMS spam, and lowers the potential for phone number harvesting associated with data breaches. Historically, the push for these services has stemmed from growing concerns surrounding data privacy and the increasing prevalence of surveillance.
