-> ℹ️ In this repository, changes don't happen that often and the library gets updated very rarely. However, this is **not** an abandoned project. Since the code is relatively simple, follows the specifications of the two RFCs, and has good test coverage, there is hardly any need to change anything.

Since the code is relatively simple, follows the specifications of the relevant RFCs, and has good test coverage, there is little need to change anything.
 
-> ℹ️ If you want to use this library in conjunction with the Google Authenticator app (or similar apps), please carefully read the chapter [Google Authenticator](#google-authenticator), especially the remarks regarding the Base32-encoded secret and the plain text secret length limitation. Most problems arise from not following the two remarks correctly.
