Almost every site on the Internet now has a URL that begins with "https". And this very "s" means that your connection is secured using SSL.
What is this "SSL"? Technically speaking, it is a cryptographic protocol for encrypting data as it travels over a computer network.
When using SSL, a secure tunnel is created between the server and the client, from which it is impossible to intercept any data, because it will be in the form of a complete gibberish, which will take a couple of years or more to decipher.
Thanks to such strong protection, you can always be sure that even connecting from a public Wi-Fi to the service via an SSL connection, your data will be safe from third parties.
⚠️ Please note: SSL will not be able to protect your data if malware is installed on your phone/laptop or on the server you are connecting to. An HTTPS connection can only protect the data link, not the endpoints.
