Signal and Threema in care: Encryption is only part of approval
Encrypted messages do not automatically solve account management, device loss or record keeping. Assess the whole workplace workflow.

Contexto y fuentes
Information security includes endpoints, local copies, notifications, administration and recipient selection as well as message encryption. The EDPB presents technical and organisational controls as complementary measures, not a single-feature guarantee. [1]
Resident information requires an appropriate legal basis, with additional conditions for health data. Establish the provider's role from the actual service rather than automatically classifying every provider as a processor. [2]
Where professional secrets are involved, authorised disclosure under section 203 of the German Criminal Code also requires assessment. Neither a consumer label nor a business label answers that question alone. [3]
Alcance y límites
No current product-specific claim about Signal or Threema backups, phone-number requirements or administrative features is made here. Private devices are not universally prohibited by law, but need a viable controlled framework.
Explicación sencilla
Fictional example: An encrypted care group retains a former employee after departure. The encryption works; access management fails.
Recomendaciones prácticas
Our recommendation: Test managed account creation, joining groups and removing access. Ask for a demonstration of leaver and lost-device handling. Decide explicitly on private devices, local storage and backups.
Remote deletion only helps when technically available and operationally usable. Set permitted information types and a documentation process. Reassess after changes to the plan or configuration. Approve a bounded workflow rather than endorsing a brand without conditions.
