Problem in Sim800L Http connectivity when httpNodeAuth Activated

[iotdevv]

hello
i have a problem with http post/get methods with Sim800L module
i enabled httpNodeAuth to protect http connection with a user/pass
i tested post/get methods with Postman and i get 200/Ok response
but with sim800l i have problem . as you know when you enable httpNodeAuth you should send your request with this format :
http://user:password@YourIPAddress:1880/path
but it seems with this format sim800L cant make http connection

Note: When i disable httpNodeAuth i have any problem with Sim800L http connection to Node-Red server!

Simple authentication (user/pass) has no security effect because the username and password is transferred as clear text. Same as if you stick your key of your bike with tape on the bike itself.
Https or other encryption is necessary but that needs memory and some calculation power ... perhaps take a look at an esp32? And find a library or firmware that can use the serial at commands for your gsm card.
