==Privacy==
Some messaging services that are not designed for privacy require a unique phone number for sign-up, as a form of identity verification and to prevent users from creating multiple accounts.
 
Some messaging services that do not solely focus on a mobile-first experience, or enforce [[SMS]] authentication, may allow email addresses to be used for sign-up instead.
 
Some messaging services offer greater flexibility and privacy, by allowing users to create more than one account to compartmentalize personal & work purposes, or not requiring personally identifiable information for sign-up.
 
To find out if the software has [[end-to-end encryption]], see "media" table below.

==Miscellaneous==
Messaging services can operate around different models, based on security and accessibility considerations.<ref name="messenger-model-design-decisions">{{cite web|url=https://wireapp.medium.com/product-design-decisions-for-secure-messengers-e8a5e7d1a373|title=Product design decisions for secure messengers - by Wire - Medium|date=31 May 2017 }}</ref>
 
A mobile-focused, phone number-based model operates on the concept of primary and secondary devices. Examples of such messaging services include: [[WhatsApp]], [[Viber]], [[Line (software)|Line]], [[WeChat]], [[Signal (messaging app)|Signal]], etc. The primary device is a mobile phone and is required to login and send/receive messages. Only one mobile phone is allowed to be the primary device, as attempting to login to the messaging app on another mobile phone would trigger the previous phone to be logged out. The secondary device is a computer running a desktop operating system, which serves as a companion for the primary device. Desktop messaging clients on secondary devices do not function independently, as they are reliant on the mobile phone maintaining an active network connection for login authentication and syncing messages.
 
A multi-device, device-agnostic model is designed for accessibility on multiple devices, regardless of desktop or mobile. Examples of such messaging services include: [[Skype]], [[Facebook Messenger]], [[Google Hangouts]] (subsequently [[Google Chat]]), [[Telegram (software)|Telegram]], [[ICQ]], [[Element (software)|Element]], [[Slack (software)|Slack]], [[Discord]], etc. Users have more options as usernames or email addresses can be used as user identifiers, besides phone numbers. Unlike the phone-based model, user accounts on a multi-device model are not tied to a single device, and logins are allowed on multiple devices. Messaging services with a multi-device model are able to eliminate feature disparity and provide identical functionality on both mobile and desktop clients. Desktop clients can function independently, without relying on the mobile phone to login and sync messages.

{{Reflist|group=lower-alpha|refs=
{{Portal|Technology}}
<ref name="screen-destroy">Screenshot protection and self-destructing messages provide only basic protection against casual/inadvertent logging of messages by users.</ref>
<ref name="asymmetric-encrypt-session-key-for-symmetric-encrypt-message">In [[symmetric-key algorithm|symmetric cryptography]], the same key is used for encryption and decryption. Knowledge of this key needs to be limited to the two communication partners to ensure confidentiality. As asymmetric algorithms are relatively [[Public-key cryptography#Computational cost|computationally costly]] in terms of speed, as compared to symmetric cryptography, the [[session key]] may be encrypted / decrypted by a asymmetric algorithm and use a much faster symmetric algorithm to encrypt and decrypt messages, reducing computational cost (increasing speed).</ref>
<ref name="OpenSourceLicense">For transparency to the public, the [[source code]] of the [[encryption]] [[algorithms]], and its implementation into a messenger, should be subject to public [[audit]]ing—which may disclose flaws or implementation failures. Whereas, a company offering a messenger which does not reveal the source must be blindly trusted. In general it is recommended to not trust closed source encryption.</ref>
<ref name="Decentralized">If a messenger relies on a [[client-server|central server]], the setup is closed and may be surveilled. To counter this, [[decentralized computing]] architectures have been developed via a peer-to-peer technology, open source chat servers (easily setup by anyone) and/or [[Federation (information technology)|federated]] protocols. An architecture in which all the messages do not pass through a central server lessens a single point for surveillance.</ref>
<ref name="ContactVerification">The clients have a built-in method for users to verify the identity of correspondents they are speaking with and the integrity of the channel, even if the service provider or other third parties are compromised. Two possible ways of doing this are through:
#An interface for users to view the fingerprint (hash) of their correspondent's public keys as well as their own, which users can verify manually or out-of-band.
#A key exchange protocol with a short-authentication-string comparison. An example is the [[Socialist millionaire]]'s protocol.
The solution should verify a binding between the users and the cryptographic channel.</ref>
<ref name="Asym">The critical advantage in an [[asymmetric cryptography|asymmetric key]] system is that copies of keys do not need to be sent between communicators. This prevents a third party from copying a key while it is in transit, and preventing the third party from spying on all future messages. In addition, if one key was copied by a third party, only messages to the holder of the key would be compromised, not the messages to the other party in the communication. However, asymmetric algorithms are relatively [[Public-key cryptography#Computational cost|computationally costly]] in terms of speed, as compared to symmetric cryptography. The most common asymmetric cryptography algorithm is the [[RSA (algorithm)|RSA Algorithm]]. [[Public-key cryptography#Examples|Alternative asymmetric algorithms]] are [[Digital Signature Algorithm]] (DSA), [[Elliptic curve cryptography]] (ECC), [[ElGamal encryption|ElGamal]] and [[NTRUEncrypt|NTRU]]. NTRU is regarded not vulnerable to decryption by quantum computing.</ref>

<ref name="keysize">The [[key size]] describes the length of the needed mathematical operation. Simply spoken, the longer the key, the longer it takes to crack it. Today a key size of 2048 for asymmetric keys is recommended.</ref>
<ref name="forwardSecrecy">[[Forward secrecy]] describes the option to change the encryption key every session or even instant. This may be implemented by [[Off-the-Record Messaging]] (OTR)</ref>
<ref name="Multiple">[[Multiple encryption]] is the process of encrypting an already encrypted message one or more times, either using the same or a different algorithm.</ref>
<ref name="clientside">The client uses [[client-side encryption]] to [[cyphertext|encrypt]] the data before it is transmitted, with a key that is stored on the device of the user, not on a remote server on the internet.</ref>
<ref name="groupChatandfiletransfer">Some messengers offer [[Groupchat]] and file transfer. These features should transfer only encrypted bytes. Encrypted file transfer may be implemented by [[Off-the-Record Messaging]] (OTR)</ref>
<ref name="IP">[[Public key]]s are used to identify users. A user's [[IP address]] can in some cases be related to his or her public key. Messengers that do not relate the user's public key to the user's IP address are considered more secure. This offers more security because the IP cannot be targeted to gain access to the private key. If an attacker knows the IP related to a public key, he or she can try to get on the [[remote machine]], download and decrypt the [[private key]] and thus decrypt all encrypted communication.</ref>
<ref name="proxy">[[Proxies]] and [[Tor (anonymity network)|Tor]] might prevent an [[IP address|IP]] from being related to the [[public key]].</ref>
<ref name="transport">Not all messengers support the same [[transport layer|transport protocols]] like [[Transmission Control Protocol|TCP]], [[User Datagram Protocol|UDP]] and [[SCTP]].</ref>
