TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations. This is useful if TLS is used in performance-constrained environments with limited CPU power.
BPSK (also sometimes called PRK, phase reversal keying, or 2PSK) is the simplest form of phase shift keying (PSK). It uses two phases which are separated by 180° and so can also be termed 2-PSK. It does not particularly matter exactly where the constellation points are positioned, and in this figure they are shown on the real axis, at 0° and ...
In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. [ 1 ] Key
In WPA2-protected WLANs, secure communication is established through a multi-step process. Initially, devices associate with the Access Point (AP) via an association request. This is followed by a 4-way handshake, a crucial step ensuring both the client and AP have the correct Pre-Shared Key (PSK) without actually transmitting it.

PSK is used so widely that listing all its usages would be an article of its own probably; it started with the NASA space program in the '60s I believe. Originally, and imo more helpfully, the applications section at the bottom so you only got to it once you knew what/where the PSKs are.
AOL has created a process where members can verify account ownership through photo ID. This process has been created to keep account recovery as seamless as possible while maintaining account and personal security at all times.
Mutual authentication supports zero trust networking because it can protect communications against adversarial attacks, [7] notably: . Man-in-the-middle attack Man-in-the-middle (MITM) attacks are when a third party wishes to eavesdrop or intercept a message, and sometimes alter the intended message for the recipient.
