Signal is a free and open-source messaging app that focuses on privacy and security. It allows you to send text messages, make voice and video calls, and share files with end-to-end encryption. This means that only you and the person you're communicating with can read or listen to your messages and calls.
Signal serves as a vital communication tool during disasters or outages of primary systems. It's robust end-to-end encryption ensures secure and reliable communication, even in critical situations. The platform's streamlined focus on messaging and calling enhances its reliability when other channels may be compromised. Additionally, Signal's cross-platform compatibility ensures seamless connectivity across various devices, facilitating swift and secure information sharing. This makes Signal an indispensable backup communication solution for maintaining operational continuity during unforeseen events.
Signal is being rolled out for the Faculty of Law's Crisis Response Team as a backup communication channel should primary channels such as email and MS Teams fail.

Q: I've clicked on the invitation link, but it is not working.
A: You must install the app before joining a Signal Messenger Group. If you are still experiencing issues, please get in touch with the Law IT Help Desk.
Q: The app is asking me for my phone number. Can I set up the app without a phone number?
A: Unfortunately, no. The app requires verifying the user by sending an SMS or phone call.
Q: When setting up the app, I'm asked if I want to allow notifications and alerts from the app, should I?
A: It is recommended that notifications and alerts from the app be allowed to ensure you receive important messages promptly.
Q: When setting up the app, I'm asked if I should allow access to my phone's contacts, should I?
A: There is no need to share your phone's contacts. Signal Messenger Groups links can be used to add people to a group.
Q: When setting up the app, I see an option "Who can find me by number?" and it defaults to Everyone. Should I change this?
A: You can choose what is most appropriate for you; there is no need to make your number searchable in Signal. You can request that the group administrator send you a Signal Messenger Group link when joining groups.
Q: How long will the messages in Signal stay?
A: Each group can have a unique message retention period, which can be adjusted as needed. The retention period for the Faculty of Law Crisis Response Team group has been set to 1 week to align with our MS Team retention protocol.
Q: Do you need to remember the PIN I used to set up the app?
A: Yes, once in a while, the app asks you to verify yourself by inputting your PIN
