Some time ago I was working in a freelance gig. I was the backend developer and the front end guy and I had some differences in our postman collections, so I asked him to email me his exported json collection.

When he emailed me, it was really funny to see his signature, which included all the courses he had and his degrees and whatnot.

like dude, "I didn't wanted your CV, I just wanted the collection"

I'll try to pay back some smaller credit by one large credit...

Hence I need to contact the banks and get one (!) fucking frigging stupid piece of paper which lists the account number and the amount of money I need to pay back.

Sounds simple ...

Well.

One bank just answered my email request by sending me that piece of paper. Except they didn't have any validation of my identity.

Yes. They answered the request of 'I want to pay back the credit in full, can u send me the necessary documents?' (more formal of course) with confidential data without any more credibility than my email address.

YAY.

Another bank requests a telephone call for identity validation and sending back a signed form via postal service...

Another bank just needs a PDF sent via mail with an electric signature (yeah. They were aware of what that means - I was shocked and confused) or a "qualified signature matching previous documents" (translated from German).

The last one offers a WhatsApp number - send a GIF / JPG or video and we answer directly.

I need to reach a higher state than drunk.

It's not funny to know how confidential data gets mistreated by companies who should have the highest security.
