Telstra fail with fixed default password

[Petermint]

Telstra sold an application with a rather stupid flaw, a fixed username/password. I wonder if there is any application that bad on Linux?

Certificates and other security measures still end up with passwords even if they are called something else. Some products let you make up passwords and are exposed until you provide a password, which makes some people enter a simple password with the intention of replacing it later.

One time random starter passwords are good if they do not use weird characters that do not reproduce with some fonts or are really confusing when they use O0 combinations.

The situation becomes complex when you have multiple connections each with a different configuration/login process. You then have to write down 42 sets of access details.
