+# Thunderbird "Export for Mobile" QR code format (version 1)
+
+This specification describes the data format of the QR code payload used by Thunderbird desktop to export account to
+Thunderbird Mobile.
+
+## Specification versions
+
+### Version 1 (2025-02-06)
+
+Initial version.
+
+## Terms
+
+### Reader
+
+A reader is the software parsing the QR code payload after it has been scanned, e.g. Thunderbird for Android.
+
+### Writer
+
+A writer is the software creating QR codes that follow this specification, e.g. Thunderbird for desktop.
+
+### Account
+
+For the purpose of this specification an account is the combination of an `IncomingServer` object and the
+`OutgoingServerGroups` object that is directly following this `IncomingServer` object.
+See [root element](#root-element).
+
+### Version
+
+Whenever this document refers to a version without qualifier, the [specification version](#specification-versions) is
+meant. It is different from the [format version](#formatversion) that is expected to stay the same until a
+backward-incompatible change to the data format needs to be made.
+
+## General structure
+
+The QR code payload is JSON, encoded using UTF-8. The data objects like incoming server, outgoing server, and identities
+are mapped to JSON arrays.
+
+The data format is extensible by allowing arrays to contain additional elements from the ones specified in the initial
+version. This applies to all arrays unless otherwise stated, but it is usually also explicitly spelled out.
+For forward-compatibility a reader must ignore additional array values not listed in the version of the specification it
+implements. A writer must not add elements to an array that are not part of the version of the specification it
+implements.
+
+### Motivation
+
+We chose JSON because it's a widely supported format that is easily extensible, i.e. it's easy to add additional
+properties later. We decided to use nested JSON arrays because it leads to compact output and space in QR codes is very
+limited.
+
+The downside of using JSON arrays is that it's most likely more work for implementations. For most object oriented
+languages there exist libraries to map objects to JSON objects. However, library-assisted mapping of objects to JSON
+arrays is not something that is typically available.
+Another issue worth mentioning is that using JSON arrays makes the output harder to read for humans.
+
+This is not a great data format. But it's one that seems to work well within the constraints of a QR code.
+
+### Compatibility
+
+If you intend to create a reader that is not using all of the information present in the payload, you must still
+validate all of the properties, even the ones you're not using. This is to avoid situations where QR codes are being
+recognized as valid by one (incomplete) reader but not another (full) reader.
+
+### Multiple QR codes
+
+The data format supports encoding an unlimited number of accounts to be able to export multiple accounts at the same
+time. However, the payload size of a QR code is limited. So when exporting multiple accounts, multiple QR codes might
+have to be used. The `SequenceNumber`/`SequenceEnd` mechanism (see below) is used to signal to the reader how many
+QR codes are part of an export and in which order.
+
+Note: This data format doesn't support spreading data for one account over multiple QR codes. So the amount of data that
+can be used to encode one account is limited by the maximum QR code size. So far this hasn't been a problem in practice.
+
+It's up to the writer to decide on a strategy of how many accounts to store in one QR code. But since larger QR codes
+are harder to scan, it's probably a good idea to aim for a specific (maximum) QR code size, rather than using a fixed
+number of accounts per QR code.
+
+## Data format
+
+### Root element
+
+- Available since: version 1
+- Type: Array
+
+The root element of the JSON document is an array containing the following elements in this order:
+
+- `FormatVersion`
+- `MiscellaneousData`
+- `IncomingServer`
+- `OutgoingServerGroups`
+
+The array may contain additional `IncomingServer` and `OutgoingServerGroups` elements. But they always have to appear in
+pairs in exactly this order because only together they make up an account.
+
+### `FormatVersion`
+
+- Available since: version 1
+- Type: Integer
+- Value: 1
+
+The version of the data format. This only needs to change if the existing mechanism for extensibility isn't sufficient
+and the data format itself has to be changed in a backward-incompatible way. Of course the new data format might not
+use a JSON array as root element. In that case the incompatibility can be detected without this property.
+
+This document only describes format version 1. If a reader encounters any other value, it needs to either explicitly
+support that specific version or fail with an error.
+
+### `MiscellaneousData`
+
+- Available since: version 1
+- Type: Array
+
+This array contains the following elements in this order:
+
+- `SequenceNumber`
+- `SequenceEnd`
+
+Future versions of this specification may add additional values to this array.
+
+### `SequenceNumber`
+
+- Available since: version 1
+- Type: Integer
+
+Information about multiple accounts might not fit into a single QR code. This property contains the 1-based index of
+the current QR code. A reader can use this information together with `SequenceEnd` to figure out how many QR codes in a
+sequence have already been read and how many are still missing.
+
+### `SequenceEnd`
+
+- Available since: version 1
+- Type: Integer
+
+Information about multiple accounts might not fit into a single QR code. This property contains the number of QR codes
+used for a single export operation. A reader can use this information together with `SequenceNumber` to figure out how
+many QR codes in a sequence have already been read and how many are still missing.
+
+### `IncomingServer`
+
+- Available since: version 1
+- Type: Array
+
+This type contains properties that are only present once in an account, mostly information about the incoming server .
+The first element in this array is `IncomingProtocol`. Its value determines the contents of the rest of the array.
+
+For forward-compatibility a reader must skip reading an account when an unsupported `IncomingProtocol` value is
+encountered.
+
+Note: Since the size of this array depends on the value of `IncomingProtocol`, future specifications can only add
+properties on a per protocol basis.
+
+### `IncomingProtocol`
+
+- Available since: version 1
+- Type: Integer
+- Values:
+  - 0 (`IMAP`; available since: version 1)
+  - 1 (`POP3`; available since: version 1)
+
+For the values 0 and 1 the contents of the `IncomingServer` array are as follows:
+
+- `IncomingProtocol`
+- `Hostname`
+- `Port`
+- `ConnectionSecurity`
+- `AuthenticationType`
+- `Username`
+- `AccountName` (optional)
+- `Password` (optional)
+
+For forward-compatibility a reader must skip reading an account when an unsupported `IncomingProtocol` value is
+encountered. It must also skip the account if any of the other properties contain unsupported values.
+
+A writer may omit optional elements from the array if the subsequent elements are also omitted.
+
+#### Writing and reading `AccountName`
+
+If the account name is equal to the email address of the first identity, the writer may omit the value. If the element
+can't be omitted (because one of the following elements is present), `null` or the empty string may be used instead.
+
+A reader must use the email address of the first identity as account name if `AccountName` is omitted or its value is
+`null` or the empty string.
+
+#### Writing and reading `Password`
+
+If the writer doesn't want to include the password, it may omit the `Password` element.
+
+For forward-compatibility a reader must treat a `Password` value of `null` or the empty string like an omitted
+password.
+
+### `Hostname`
+
+- Available since: version 1
+- Type: String
+
+A server hostname. Currently only ASCII-only hostnames are allowed. This includes the ASCII Compatible Encoding (ACE) of
+Internationalized Domain Names (IDN).
+
+### `Port`
+
+- Available since: version 1
+- Type: Integer
+- Values: 1-65535
+
+The TCP port used by an incoming or outgoing server.
+
+### `ConnectionSecurity`
+
+- Available since: version 1
+- Type: Integer
+- Values:
+  - 0 (`Plain`; available since: version 1)
+  - 1 (legacy, do not use; reserved since: version 1)
+  - 2 (`AlwaysStartTls`; available since: version 1)
+  - 3 (`Tls`; available since: version 1)
+
+Describes if and how to use TLS to secure the connection to a server.
+
+### `AuthenticationType`
+
+- Available since: version 1
+- Type: Integer
+- Values:
+  - 0 (`None`; available since: version 1)
+  - 1 (`PasswordCleartext`; available since: version 1)
+  - 2 (`PasswordEncrypted`; available since: version 1)
+  - 3 (`Gssapi`; available since: version 1)
+  - 4 (`Ntlm`; available since: version 1)
+  - 5 (`TlsCertificate`; available since: version 1)
+  - 6 (`OAuth2`; available since: version 1)
+
+The authentication method to use.
+
+### `Username`
+
+- Available since: version 1
+- Type: String
+
+The username to use for authentication.
+
+### `AccountName`
+
+- Available since: version 1
+- Type: String
+
+The name of the account. If the value is `null` or the empty string, a reader must use the email address of the first
+identity as the value of the account name.
+
+A reader must use the email address of the first identity it is able to successfully read.
+
+Note: This can lead to the reader using a different account name than the writer intended. But an unintended account
+name is deemed preferable to the whole account having to be skipped because the reader doesn't support reading the first
+identity.
+
+### `Password`
+
+- Available since: version 1
+- Type: String
+
+The password to use for authentication.
+
+### `OutgoingServerGroups`
+
+- Available since: version 1
+- Type: Array
+
+The array contains one or more `OutgoingServerGroup` elements.
+
+### `OutgoingServerGroup`
+
+- Available since: version 1
+- Type: Array
+
+This array contains the following elements in this order:
+
+- `OutgoingServer`
+- `Identity`
+
+The array may contain additional `Identity` elements.
+
+A reader must skip the `OutgoingServerGroup` if it fails to read the `OutgoingServer` or all `Identity` elements.
+
+### `OutgoingServer`
+
+- Available since: version 1
+- Type: Array
+
+The first element in this array is `OutgoingProtocol`. Its value determines the contents of the rest of the array.
+
+Note: Since the size of this array depends on the value of `OutgoingProtocol`, future specifications can only add
+properties on a per protocol basis.
+
+### `OutgoingProtocol`
+
+- Available since: version 1
+- Type: Integer
+- Values:
+  - 0 (`SMTP`; available since: version 1)
+
+For the value 0 the contents of the `OutgoingServer` array are as follows:
+
+- `OutgoingProtocol`
+- `Hostname`
+- `Port`
+- `ConnectionSecurity`
+- `AuthenticationType`
+- `Username`
+- `Password` (optional)
+
+For forward-compatibility a reader must skip reading the `OutgoingServerGroup` when an unsupported `OutgoingProtocol`
+value is encountered. It must also skip the `OutgoingServerGroup` if any of the other properties contain unsupported
+values.
+
+#### Writing and reading `Password`
+
+If the writer doesn't want to include the password, it may omit the `Password` element.
+
+For forward-compatibility a reader must treat a `Password` value of `null` or the empty string like an omitted
+password.
+
+### `Identity`
+
+- Available since: version 1
+- Type: Array
+
+This array contains the following elements in this order:
+
+- `EmailAddress`
+- `DisplayName`
+
+A reader must skip this identity if any of the elements contain unsupported values.
+
+Future versions of this specification may add additional values to this array.
+
+### `EmailAddress`
+
+- Available since: version 1
+- Type: String
+
+The email address to use for outgoing messages.
+
+Currently only ASCII-only email addresses are allowed.
+
+### `DisplayName`
+
+- Available since: version 1
+- Type: String
+
+The name to use in outgoing messages.
