`b64decode` is a method in Python's `base64` module that decodes a Base64 encoded string into its original binary data. The method takes a single argument, which is the Base64 encoded string to be decoded. For example:
```python
import base64
encoded_string = "SGVsbG8gV29ybGQh"
decoded_data = base64.b64decode(encoded_string)
print(decoded_data) # b'Hello World!'
```
In this example, the `b64decode` method takes the encoded string "SGVsbG8gV29ybGQh" and returns the original binary data, which is the string "Hello World!" in bytes format.

`b64decode` is a method in the `base64` module in Python. It is used to decode a Base64 encoded string back into its original form.
Here's an example of how you can use it:
```python
import base64
encoded_string = "SGVsbG8gV29ybGQh" # Base64 encoded string
decoded_bytes = base64.b64decode(encoded_string) # Decode the string
decoded_string = decoded_bytes.decode('utf-8') # Convert bytes to string
print(decoded_string) # Output: "Hello World!"
```
In the above example, the `b64decode` function decodes the `encoded_string` variable, which contains a Base64 encoded string, into bytes. The `decode` method is then used to convert those bytes back into a string using the 'utf-8' encoding. The resulting decoded string is then printed.
pwd = b64decode(self.text).decode('utf-8')
This line of code is decoding a Base64 encoded string (which is stored in the variable `self.text`) and then decoding it into a UTF-8 encoded string. The resulting string is then stored in the variable `pwd`.
Note that `b64decode()` is a function from the `base64` module in Python, which takes a Base64 encoded string as input and returns the decoded bytes. The `decode()` method is then called on these bytes to convert them into a UTF-8 encoded string.
