For secret key authentication to work, the two parties to a transaction must share a cryptographic session key which is also secret, known only to them and to no others. The key is symmetric; that is, it is a single key used for both encryption and decryption.
Open the Authenticator app on your new phone and tap Begin > Scan barcode. Scan the QR code displayed on Google's website with the Authenticator app, then enter the six-digit code to verify everything is working properly. Once that's done, the codes on your old device will no longer be valid.

Microsoft Authenticator 6 digit code.
It is actually an asymmetric key-pair with a length typically between 256 and 4,096 bits depending on the digital signature algorithm used. Such a key usually has a lifetime of several years, and the private key will often be protected using an HSM.
A shared secret key is used by mutual agreement between a sender and receiver for encryption, decryption, and digital signature purposes. A shared secret key uses a text file that contains the key material for cryptographic operations.
Shared key encryption uses one key to encrypt and decrypt messages. For shared key cryptography to work, the sender and the recipient of a message must both have the same key, which they must keep secret from everybody else.

Authenticator apps work the same way text-based 2FA does, but instead of having a code sent to you via text, the code appears in the app. The code also changes every 30 seconds or so as an added measure of protection — it's next to impossible for a hacker to guess at the right code when it changes so frequently.
You can have Google Authenticator on two or more devices and use them simultaneously, or as a backup, in case your phone will get lost, stolen, or damaged.
During setup, the service provider generates an 80-bit secret key for each user (whereas RFC 4226 §4 requires 128 bits and recommends 160 bits). This is transferred to the Authenticator app as a 16, 26 or 32 character base32 string, or as a QR code.
