Encryption or misunderstood?

Hello, here is the problem I encountered : ----------------------------------------------------------------------------------- Chef, I recovered a dark email . I'm afraid to go into this strange world.

So, it appears to be a Beaufort cipher

Beaufort cipher
The Beaufort cipher, created by Sir Francis Beaufort, is a substitution cipher similar to the Vigenère cipher, with a slightly modified enciphering mechanism and tableau. Its most famous application was in a rotor-based cipher machine, the Hagelin M-209. The Beaufort cipher is based on the Beaufort square which is essentially the same as a Vigen...

Beaufort Cipher (online tool) | Boxentriq
Tool to decrypt Beaufort ciphers. The Beaufort cipher is named after Sir Francis Beaufort. It is similar to the Vigenère, but the encryption and decryption is reciprocal (the encryption and decryption algorithms are the same). The Beaufort cipher is a polyalphabetic cipher.

Thank you, but I understood the messages of the last part (a username and a password, but I didn't post the real ones xD), but I still can't decode this this string of characters(I thought at the beginning a web link or a server address since it gives the username and password), why does he talk about Webmail?

It might decode into something like a URL or a part of an email It could be a running key, too But the problem with the Beaufort cipher is that you can't use digits for the key, it's just letters
