## End-to-end Encrypted Contact Methods

### Preferred

Whenever possible, use the following contact methods; they allow verification to mitigate man-in-the-middle attacks, have high security, and reasonable privacy.

Use the keys for each contact method to verify my devices.
Note: Verification does not verify a person, only their devices, and can be defeated via coercion or other force.

### Metadata-free

If metadata leakage is an issue for you, you can use the following contact methods.
Note: These services do not have verification functionality and will be treated as less secure; unless you really need to use these services, use a preferred method instead.

## Non-private Contact Methods

The following contact methods do not utilise end-to-end encryption, or I do not use such functionality; they are suitable for public contact only, including directly and groups. Do not use these methods if confidentiality and/or privacy is required.
