Server-side Application: This consists of an application (client) hosted on a web server. Users access the application using an HTML based user agent. Client credentials and tokens issued are stored on the web server and are inaccessible to the user.
If you have integrated with Yahoo using OAuth 1.0a, you do not need to re-authorize access to your app. Using the Explicit Grant flow, you can provide your original refresh token to receive a new OAuth 2.0 access token. For more information, refer to Step 5: Exchange refresh token for new access token.
When you set up TOTP software token MFA in your user pool, your user signs in with a user name and password, then uses a TOTP to complete authentication. After your user sets and verifies a user name and password, they can activate a TOTP software token for MFA. If your app uses the Amazon Cognito hosted UI to sign in users, your user submits their user name and password, and then submits the TOTP password on an additional sign-in page.
If you haven't activated TOTP software token MFA for the user pool, Amazon Cognito can't use the token to associate or verify users. In this case, users receive a SoftwareTokenMFANotFoundException exception with the description Software Token MFA has not been enabled by the userPool. If you deactivate software token MFA for the user pool later, users who previously associated and verified a TOTP token can continue to use it for MFA.
When your user pool requires TOTP for a user who has not configured it, your user receives a one-time access token that your app can use to activate TOTP MFA for the user. Subsequent sign-in attempts fail until your user has registered an additional TOTP sign-in factor.
After you create a user, and the user sets their initial password, Amazon Cognito issues one-time tokens from the hosted UI to the user. If you set a permanent password for the user, Amazon Cognito issues one-time tokens when the user first signs in.
Amazon Cognito doesn't issue one-time tokens to an administrator-created user who signs in with the InitiateAuth or AdminInitiateAuth API operations. After your user succeeds in the challenge to set their initial password, or if you set a permanent password for the user, Amazon Cognito immediately challenges the user to set up MFA.
If a user in a user pool that requires MFA has already received a one-time access token but hasn't set up TOTP MFA, the user can't sign in with the hosted UI until they have set up MFA. Instead of the access token, you can use the session response value from an MFA_SETUP challenge to InitiateAuth or AdminInitiateAuth in an AssociateSoftwareToken request.
When a user first signs in, your app uses their one-time access token to generate the TOTP private key and present it to your user in text or QR code format. Your user configures their authenticator app and provides a TOTP for subsequent sign-in attempts. Your app or the hosted UI presents the TOTP to Amazon Cognito in MFA challenge responses.
When your user chooses TOTP software token MFA, call AssociateSoftwareToken to return a unique generated shared secret key code for the user account. You can authorize AssociateSoftwareToken with either an access token or a session string.
If the VerifySoftwareToken operation returns an ERROR response, make sure that the user's clock is correct and that they have not exceeded the maximum number of retries. Amazon Cognito accepts TOTP tokens that are within 30 seconds before or after the attempt, to account for minor clock skew. When you have resolved the issue, try the VerifySoftwareToken operation again.
Currently, you can't delete a user's TOTP software token. To replace your user's software token, associate and verify a new software token. To deactivate TOTP MFA for a user, call SetUserMFAPreference to modify your user to use no MFA, or only SMS MFA.
It looks like, Yahoo requires this token with different encoding. On \" \" if you try to encode your \"CLIENT_ID:CLIENT_SECRET\" with \"Windows-1254\" as destination charset, you will receive the expected result. So, it looks like both encoding and decoding here is done keeping \"Windows-1254\" charset in place.
One of the earlier stories around tokens and NFTs this year was from Decrypt, a crypto publisher, which created its own set of reward tokens that were distributed when audiences downloaded and engaged with content in its app. In March, the publishers began encouraging app usage by giving out three tokens for reading an article, one token for reacting to a post with an emoji and two tokens for sharing the article.
I may be missing the point of your response but to not have a second factor whether that be a proper second factor or a secondary primary factor would not be ideal. The whole case for 2FA is for the very reason as discussed in this article. If your username and password is compromised which seems to be trivial in this day and age because of the lack of security with these on line accounts then having that verification code sent via text or generated using an app or an RSS token generator on a key fob prevents anyone else from using your account unless they got hold of this item too which is less likely. Many banks that I know of use either a key fob type generator or provide customers with USB payment card readers in order to log in on line. Is it also too inconvenient to have this on you in order to hopefully stay protected. We are not living back in the stone age, users have to make an effort too, Those of us who can should and those that cant should be assisted in some way by others they trust.
Spell Token (SPELL) is a reward token associated with abracadabra.money, a lending platform that uses interest-bearing tokens (ibTKNs) as collateral to borrow a USD-pegged stablecoin called Magic Internet Money (MIM). Abracadabra uses the Kashi Lending Technology pioneered by SushiSwap (SUSHI) to provide isolated lending markets that allow users to adjust their risk tolerance according to the collateral they decide to use. Users can deposit collateral and borrow MIM against it. Abracadabra also offers yield farming opportunities, where users can stake their liquidity provider (LP) tokens to farm SPELL. This facilitates better liquidity for certain cryptocurrency pairs, currently Ether (ETH)-Spell Token (SPELL) and Magic Internet Money (MIM)-LP 3pool Curve (3CRV). Furthermore, users can also open leveraged farming positions using borrowed MIM from their interest-bearing collateral.
One of the features of using this technology is that users can leverage their interest-bearing token positions. Users borrow against their positions and then again borrow against the borrowed stablecoin, creating several loops and thereby increasing their leverage. All of this is done in one transaction, which is why the user only pays a gas fee once.
Spell Token (SPELL) can be farmed by providing liquidity in one of the different pools. SPELL can also be staked, and staked tokens accrue a share of the platform fees (interest, borrowing fees, and 10% of the liquidation fee for certain markets), which auto-compound.
SPELL will follow a ten-year halving model, which will cut in half the rewards distributed every year. 50% of team tokens are to be issued in the first year, 25% in the second, and 12.5% in the third and fourth years. Each week, 624 million SPELL are emitted. SPELL is also used as a governance token, with users having voting power according to how much they have staked.
To connect to Outlook.com using OAuth2, seethis pageand the procedure describedherefor creating a Refresh Token and Access Token.Get your Client ID and Client secret from theMicrosoft account Developer Center.The general procedure above should work to connect toimap-mail.outlook.com, but the access token will need to be acquired asdescribed on the Outlook.com page.
When you use a Google API Client Library to handle your application's OAuth 2.0 flow, the client library performs many actions that the application would otherwise need to handle on its own. For example, it determines when the application can use or refresh stored access tokens as well as when the application must reacquire consent. The client library also generates correct redirect URLs and helps to implement redirect handlers that exchange authorization codes for access tokens.
Set the value to offline if your application needs to refresh access tokens when the user is not present at the browser. This is the method of refreshing access tokens described later in this document. This value instructs the Google authorization server to return a refresh token and an access token the first time that your application exchanges an authorization code for tokens.
You can use this parameter for several purposes, such as directing the user to the correct resource in your application, sending nonces, and mitigating cross-site request forgery. Since your redirect_uri can be guessed, using a state value can increase your assurance that an incoming connection is the result of an authentication request. If you generate a random string or encode the hash of a cookie or another value that captures the client's state, you can validate the response to additionally ensure that the request and response originated in the same browser, providing protection against attacks such as cross-site request forgery. See the OpenID Connect documentation for an example of how to create and confirm a state token.
Enables applications to use incremental authorization to request access to additional scopes in context. If you set this parameter's value to true and the authorization request is granted, then the new access token will also cover any scopes to which the user previously granted the application access. See the incremental authorization section for examples. 1e1e36bf2d
