Changelog

Sourced from flask-security-too's changelog.

Version 5.7.0

Released November 14, 2025

This release contains a set of small backward incompatible changes. Please read these notes carefully.

Features & Improvements +++++++++++++++++++++++

• (:pr:1132) Add Arabic translations (samialfattani)
• (:issue:1123) Enable forgot-password workflow for authenticated users.

Fixes +++++

• (:pr:1115) Fix broken link in docs and improve docstrings/typing for util classes.
• (:issue:1127) Add nonce to script tags if configured to support nonce-based Content-Security-Policy (ahanak).
• (:issue:1133) Remove unnecessary (optional) dependency on sqlalchemy_utils.
• (:pr:1140) Fix localization of tf_select choices.
• (:pr:1143) Support bcrypt 5.0 - See below for important compatibility concerns. This also replaces passlib with libpass for all versions.

Docs and Chores +++++++++++++++

• (:pr:1144) Update ES and IT translations (gissimo)
• (:pr:1106) Drop support for Python 3.9. This removes the dependency on importlib_resources, updates pypy to 3.10, and uses 3.12 as base python for tests/tox.
• (:pr:1112) Flip :py:data:SECURITY_USE_REGISTER_V2 default to True.
• (:pr:1117) Flip default mail package back to Flask-Mail (from Flask-Mailman).
• (:issue:1139) Change external facing terminology from 'WebAuthn Credential' to 'passkey'.
• (:pr:1142) Setting of xx_util_cls from kwargs which was deprecated in 5.6.1 has been removed. The BACKWARDS_COMPAT_UNAUTHN option (code) which has been deprecated since 5.4 has been removed.

Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++

• Flask-Security now depends on libpass (https://pypi.org/project/libpass/) for all versions. Be sure to UNINSTALL passlib, ensure the passlib directory is empty and then install libpass - we have seen reports when both are installed - it doesn't work!

  In bcrypt 5.0 they started throwing a ValueError for passwords/secrets longer than 72 bytes. It is important to know that by default Flask-Security performs a double hash - taking the secret, using HMAC(SHA512) then b64encodng the result. This means that ANY password will be longer than 72 bytes (86 to be exact). In the past bcrypt would silently truncate the input - now we have to do that explicitly. OWASP says truncation concerns are negligible: https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html#input-limits-of-bcrypt

• The default RegisterForm is now the new RegisterFormV2 - Please read :ref:register_form_migration. Flask-Security will emit a DeprecationWarning if the :py:data:SECURITY_USE_REGISTER_V2 is set to False.

• In 5.0 we changed the default mailer package to Flask-Mailman since Flask-Mail was no longer supported. Flask-Mail is again supported and is part of Pallets-Eco. Both packages are still supported based on which one an application initializes. The only backwards compatibility concern is that if you use the setup extras 'common', it will install Flask-Mail rather than Flask-Mailman.

Looks like flask-security-too is no longer updatable, so this is no longer needed.
