Starknet Accounts and Network Updates

There are already numerous implementations of Abstract Accounts, many of which provide awesome features:

the Guarded WebWallet Account from Argent
the passkey/webauthn controller from Cartridge. You can test the connection flow on their connection page
the Starksign Multisig from Equilibrium, the WebWallet from Braavos and the WebWallet from Argent
the MIT-licensed well documented and reusable Abstract Account from OpenZeppelin
Starkware provides a nice workshop about Abstract Account development and the Starknet Book has several sections about accounts and multisig.
The Cairo v0 Plugin Account provides some implementation ideas

The 2024 Starknet roadmap provides some details about the expected features. In particular, see Mattéo Georges answer in Dec 2023 that suggests the Paymaster is not yet prioritized.

Modules help to address advanced scenarios. They are often classified in 4 groups:

Roles: e.g. spending limits, associated token: vTokens, NFT(id) or Oracle, multiple factor for administrative privileges, recurring payments, alternative signatures including faceid or fingerprints, zkproof, Merkle tree for Offchain ACL
Recovery: e.g. social recovery, custodial recovery, physical devices, other secrets validation
Protection: e.g. allow/deny list, freeze account, external whitelisting, Oracle MEV protection
Modifiers: e.g. time-lock, cooldown/grace period, bonds

To dig deeper into some of the many scenarios associated with Module, you can have a look at existing implementations like:
